What is the circumference of a circle with a diameter of 3.25 meters? Estimate the circumference to the hundredths place using 3.14 for π.
The circumference of a circle can be found using the formula: C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 3.25 meters, we can substitute it into the formula:
C = 3.14 * 3.25
C ≈ 10.21 meters
Therefore, the estimated circumference of the circle is 10.21 meters.
What is the circumference of a circle with a diameter = 4 feet? Which of the following is the best estimation for the circumference?
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 4 feet, we can substitute it into the formula:
C = 3.14 * 4
C = 12.56 feet
Therefore, the exact circumference of the circle is 12.56 feet.
However, you mentioned "the following" without providing any options to choose from, so I cannot determine which estimation would be the best in this case.

My apologies for any confusion. Let's try solving it again.
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 4 feet, we can substitute it into the formula:
C = 3.14 * 4
C = 12.56 feet
Therefore, the exact circumference of the circle is 12.56 feet.
As for the estimation, let's consider the following options:
A) 14 feet
B) 13 feet
C) 12 feet
D) 11 feet
Based on the calculated exact circumference of 12.56 feet, the best estimation for the circumference would be option C) 12 feet.

The circumference of a circle is given by the formula C = 2πr, where C is the circumference, π is approximately 3.14, and r is the radius.
Given that the radius is 2.5 feet, we can substitute it into the formula:
C = 2 * 3.14 * 2.5
C = 15.7 feet
Therefore, the exact circumference of the circle is 15.7 feet.
Based on the provided options, the best estimation for the circumference to the tenths place would be 15.7 feet.

The area of a circle is given by the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius.
Given that the radius is 12 feet, we can substitute it into the formula:
A = 3.14 * 12^2
A = 3.14 * 144
A = 452.16 square feet
Therefore, the exact area of the circle is 452.16 square feet.
Based on the provided options, the best estimation for the area to the hundredths place would be 452.16 square feet.

The area of a circle is given by the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius.
Given that the diameter is 10 millimeters, we can divide it by 2 to find the radius:
Radius = 10 mm / 2 = 5 mm
Now we can substitute the radius into the formula:
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5 square mm
Therefore, the exact area of the circle is 78.5 square mm.
Based on the provided options, the best estimation for the area to the tenths place would be 78.5 square mm.
