What is the area of a circle with a radius of 12 feet? Estimate the area to the hundredths place using 3.14 for π. (1 point)
O 452.2 square feet
O 452.16 square feet
O 113.04 square feet
O 75.4 square feet
The area of a circle is given by the formula A = πr^2, where r is the radius.
Given that the radius is 12 feet, we can substitute this value in the formula:
A = π(12)^2 = 3.14 * 144 = 452.16 square feet
Therefore, the estimated area to the hundredths place is 452.16 square feet.
The answer is O 452.16 square feet.
To find the area of a circle, you can use the formula:
Area = π * r^2
where π is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
Given that the radius of the circle is 12 feet, we can substitute this value into the formula:
Area = 3.14 * 12^2
Simplifying the equation:
Area = 3.14 * 144
Calculating the product:
Area = 452.16 square feet
Therefore, the estimated area of the circle to the hundredths place using 3.14 for π is 452.16 square feet.
So, the correct answer is:
O 452.16 square feet.
