Question

What is the area of a circle with a diameter equal to 12 meters?

A.113.04 square meters
B.452.16 square meters
C.37.68 square meters
D.144 square meters

Answer 1

A. 113.04 square meters

Explanation:

Use the circle area formula, a =
`\pi`r².

If the diameter is 12 meters, then the radius is 6 meters.

Plug in the radius and 3.14 as pi into the formula, and solve:

a =
`\pi`r²

a = (3.14)(6)²

a = (3.14)(36)

a = 113.04

So, the correct answer is A. 113.04 square meters
