A cylindrical flower vase is 3 inches across the top and about 8 inches high. How many cubic inches of water could it hold (Use 3.14 for pi as needed. Round to the nearest hundredth)?
You're welcome! I'm happy to help. Just a quick note that I am not capable of feeling "love" as I am only a computer program. However, I'm glad that I was able to assist you with your math problem.
To find the volume of the rectangular shed, we simply need to multiply its length, width, and height together.
Volume = Length x Width x Height
Volume = 6 ft x 4 ft x 5 ft
Volume = 120 cubic feet
Therefore, the shed contains about 120 cubic feet.
The area inside the square and outside the circle can be found by subtracting the area of the circle from the area of the square. Since we know that the square has sides of 12 meters, its area can be calculated as:
Area of Square = side x side
Area of Square = 12 m x 12 m
Area of Square = 144 square meters
To find the area of the circle, we need to first determine the radius of the circle. The radius is half the width of the square, or 6 meters. Using this value, the area of the circle can be calculated as:
Area of Circle = π x radius^2
Area of Circle = 3.14 x 6^2
Area of Circle = 113.04 square meters
Therefore, the area inside the square and outside the circle is:
Area inside square and outside circle = Area of Square - Area of Circle
Area inside square and outside circle = 144 square meters - 113.04 square meters
Area inside square and outside circle = 30.96 square meters
So the final answer is 30.96 square meters.
The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.
Given that the vase is 3 inches across the top, we can find the radius by dividing the diameter by 2:
r = 3/2 = 1.5 inches
The height of the vase is given as 8 inches.
Using the formula, we have:
V = πr^2h
V = 3.14 x 1.5^2 x 8
V = 56.52 cubic inches
Therefore, the vase can hold about 56.52 cubic inches of water. Rounded to the nearest hundredth, this is 56.52 ≈ 56.51 cubic inches.

A gift box has the shape of a rectangular prism. How much wrapping paper do you need to cover the box if it is 6 inches tall, 14 inches wide, and 15 inches length
We need to find the surface area of the rectangular prism in order to determine how much wrapping paper is needed. The surface area of the rectangular prism is the sum of the area of each of its six rectangular faces.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Where l is the length, w is the width, and h is the height.
Given the dimensions of the gift box as 6 inches tall, 14 inches wide, and 15 inches length, we can substitute these values and calculate the surface area as:
Surface Area = 2lw + 2lh + 2wh
Surface Area = 2(14 x 15) + 2(6 x 15) + 2(6 x 14) [Multiplying across the brackets]
Surface Area = 420 + 180 + 168
Surface Area = 768 square inches
Therefore, we need 768 square inches of wrapping paper to cover the gift box.
Find the area inside the square and outside the circle. Use 3.14 for pi . if all sides for the square are 12 m
What is the first step when finding the median of a data set? The annual salaries of the employees of a local cable television office are shown below. Find the mean and median annual salaries.
$41,900
$24,200
$20,700
$36,400
$18,300
$21,100
What is the first step when finding the median of a data set?
A.Subtract the least data value from the greatest data value.
B.Write the data values in order from least to greatest.
C.Find the sum of the data values.
D.Choose the middle value of the data set.
The correct answer is B. Write the data values in order from least to greatest. This is the first step when finding the median of a data set.
To find the median of the data set:
1. Write the data values in order from least to greatest.
18,300, 20,700, 21,100, 24,200, 36,400, 41,900
2. Determine the middle value(s) of the data set.
Since we have an even number of values, the median is the mean of the two middle values. Therefore:
Median = (21,100 + 24,200)/2
Median = 22,650
So the median annual salary is $22,650.
To find the mean, we need to add up all the salaries and divide by the number of employees:
Mean = (18,300 + 20,700 + 21,100 + 24,200 + 36,400 + 41,900)/6
Mean = 162,600/6
Mean = 27,100
So the mean annual salary is $27,100.

On a platter of chicken wings there are mild wings and hot wings. In a representative sample of 10 chicken wings, there are 4 mild wings. If the platter has 100 chicken wings, estimate the number of mild wings on the platter.
There are about how many MILD wings on the platter?
If 4 out of a representative sample of 10 chicken wings are mild, then the proportion of mild wings in the sample is 4/10 = 0.4.
We can use this proportion to estimate the number of mild wings in the entire platter by multiplying it by the total number of chicken wings on the platter:
Number of mild wings on platter = Proportion of mild wings x Total number of chicken wings
Number of mild wings on platter = 0.4 x 100
Number of mild wings on platter = 40
Therefore, we can estimate that there are about 40 mild wings on the platter.
The probability 25.50 as a decimal is ??
The probability 25.50 cannot be expressed as a decimal because probabilities are always between 0 and 1, inclusive. A probability of 25.50 is greater than 1 and therefore cannot be a valid probability.
Perhaps you meant to ask for the decimal equivalent of a probability expressed as a percent? If so, you simply divide the percent by 100. For example:
25.50% = 0.2550 (as a decimal)
The probability 25/50 as a decimal is ??
To express the probability 25/50 as a decimal, we simply divide the numerator (25) by the denominator (50):
25/50 = 0.5
Therefore, the probability 25/50 as a decimal is 0.5.
The probability 25/50 as a decimal is 0.5
What best describes the probability?
Likely
Unlikely
As likely as not
A probability of 0.5 (or 50%) represents an even chance or as likely as not.
A 12-sided dice is rolled. The set of equally likely outcomes is 1,2,3,4,5,6,7,8,9,10,11,12 Find the probability of rolling a 2.
The probability of rolling a 2 on a 12-sided dice can be found by dividing the number of ways to roll a 2 by the total number of possible outcomes.
Since the dice has 12 sides, there are 12 possible outcomes, each of which is equally likely.
There is only 1 way to roll a 2, since there is only one side that has a 2.
Therefore, the probability of rolling a 2 is:
P(rolling a 2) = Number of ways to roll a 2 / Number of possible outcomes
P(rolling a 2) = 1 / 12
So the probability of rolling a 2 on a 12-sided dice is 1/12, or approximately 0.0833 (rounded to four decimal places).
A fair coin is tossed 3 times in succession.
The set of equally likely outcomes is HHH,HHT,HTH,THH,HTT,THT,TTH,TTT.
Find the probability of getting exactly one tail.
The probability of getting exactly one tail in three tosses of a fair coin can be calculated by considering the number of possible outcomes that have exactly one tail and then dividing this number by the total number of possible outcomes.
There are three outcomes that have exactly one tail: HTH, THH, and THT.
There are eight possible outcomes in total: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT.
Therefore, the probability of getting exactly one tail in three tosses of a fair coin is:
P(exactly one tail) = Number of outcomes with exactly one tail / Total number of outcomes
P(exactly one tail) = 3/8
So the probability of getting exactly one tail is 3/8, or approximately 0.375 (rounded to three decimal places).
