1. Find the circumstance of a circle with a diameter (d) of 2.25 inches. Estimate the circumference to the hundredths place.
2. Find the area of a circle whose radius (r) is 7 inches. Use the formula A=Pir^2 and pi=3.14159. Estimate the area to the hundredths place.
1. The circumference (C) of a circle can be found using the formula C = πd, where d is the diameter. Given that the diameter is 2.25 inches, we can substitute it into the formula:
C = 3.14159 * 2.25
C ≈ 7.07 inches (rounded to the hundredths place)
2. The area (A) of a circle can be found using the formula A = πr^2, where r is the radius. Given that the radius is 7 inches, we can substitute it into the formula:
A = 3.14159 * (7)^2
A ≈ 153.94 square inches (rounded to the hundredths place)
Ok for both of the answers please list all the steps you did to get the answer
1. Finding the circumference of a circle:
- Given that the diameter is 2.25 inches.
- The formula for the circumference is C = πd, where d is the diameter.
- Substitute the given value of the diameter into the formula:
C = 3.14159 * 2.25
- Calculate the product:
C ≈ 7.07 inches (rounded to the hundredths place)
2. Finding the area of a circle:
- Given that the radius is 7 inches.
- The formula for the area is A = πr^2, where r is the radius.
- Substitute the given value of the radius into the formula:
A = 3.14159 * (7)^2
- Calculate the product:
A ≈ 153.94 square inches (rounded to the hundredths place)
To determine the list that shows elevations above and below sea level in order from the lowest elevation to the highest, we need to compare the numbers and arrange them accordingly.
The options given are:
A. -400 ft, -20 ft, 350 ft, 1,200 ft
B. -20 ft, -400 ft, 350 ft, 1,200 ft
C. -20 ft, 350 ft, -400 ft, 1,200 ft
D. 1,200 ft, 350 ft, -400 ft, -20 ft
Let's analyze each option:
Option A: -400 ft, -20 ft, 350 ft, 1,200 ft
The elevation starts with a low value of -400 ft, then increases to -20 ft, and further increases to 350 ft and 1,200 ft. Therefore, this option is not in order from the lowest to the highest elevation.
Option B: -20 ft, -400 ft, 350 ft, 1,200 ft
The elevation starts at -20 ft, then decreases to -400 ft, and further increases to 350 ft and 1,200 ft. This option is also not in order from the lowest to the highest elevation.
Option C: -20 ft, 350 ft, -400 ft, 1,200 ft
The elevation starts at -20 ft, then increases to 350 ft, decreases to -400 ft, and further increases to 1,200 ft. This option is the only one where the elevations are correctly ordered from lowest to highest.
Option D: 1,200 ft, 350 ft, -400 ft, -20 ft
The elevation starts with the highest value of 1,200 ft, then decreases to 350 ft, further decreases to -400 ft, and finally increases to -20 ft. This option is also not in order from the lowest to the highest elevation.
Therefore, the correct answer is option C: -20 ft, 350 ft, -400 ft, 1,200 ft.
