See a solution process below:

#### Explanation:

The formula for the Area of a Circle is:

$A = \pi {r}^{2}$ 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:

$A = \pi {\left(12 \text{m}\right)}^{2}$

$A = \pi 144 {\text{m}}^{2}$

$A = 144 \pi {\text{m}}^{2}$

This circle would have an area of 144 square meters.
