Question

what is the exact area of a circle with a radius of 12 feet? A. 24π square feet B. 36π square feet C. 121π square feet D. 144π square feet

Answer 1

The answer is D. 144pie square feet

Answer 2

Option (d) is correct.

Area of circle =
`144\pi` square feet.

Explanation:

Given : Radius of circle is 12 feet

We have to find the area of circle with a radius of 12 feet and choose the correct option from the given options.

We know,

Area of circle =
`\pi r^2`

Where r is radius of circle.

Given radius of circle is 12 feet

Substitute r = 12 , we have,

Area of circle =
`\pi (12)^2`

Simplify , we have,

Area of circle =
`144\pi` feet²

Thus, Option (d) is correct.
