Question

What is the area of a circle with radius of 12 meters?

Answer 1

See a solution process below:

Explanation:

The formula for the Area of a Circle is:

`A = pir^2` Where:

• `A` is the Area of the Circle: what we are solving for in this problem.

• `r` is the Radius of the Circle: 21 meters for this problem

Substituting and calculating `A` gives:

`A = pi(12"m")^2`

`A = pi144"m"^2`

`A = 144pi"m"^2`

This circle would have an area of 144 square meters.
