What is the area of a circle with a radius of 12 foot? Estimate the area to the hundredths place using 3,14 for x. (1 point)
O 75,4 square feet
O 113.04 square feet
O 452.2 square feet
O 452.16 square feet
The correct answer is 452.16 square feet
To find the area of a circle, you can use the formula:
A = π * r^2
where A represents the area, π (pi) is a constant approximately equal to 3.14, and r is the radius of the circle.
In this case, the radius is given as 12 feet and x is given as 3.14.
Substituting the values into the formula, we have:
A = 3.14 * 12^2
A = 3.14 * 144
A ≈ 452.16
Therefore, the area of the circle with a radius of 12 feet is approximately 452.16 square feet.
So, the correct answer is: O 452.16 square feet.
To find the area of a circle with a given radius, you can use the formula:
Area = π * r^2
where π is approximately equal to 3.14 and r is the radius of the circle.
In this case, the radius is 12 feet. To calculate the area, substitute the value of the radius into the formula:
Area = 3.14 * (12^2)
Simplifying the equation further:
Area = 3.14 * 144
Now, multiply 3.14 by 144:
Area = 452.16 square feet
Therefore, the area of the circle with a radius of 12 feet is estimated to be 452.16 square feet.
Therefore, the correct answer is:
O 452.16 square feet
