We know that

• The area of the circle is 144pi square meters.

We need to use the following formula

$A=\pi r^2$

Replacing the given information, we have

$144\pi=\pi r^2$

Now, we solve for r

$r^2=(144\pi)/(\pi)=144\rightarrow r=√(144)=12$

This means the radius is 12 meters, now we need to find the diameter with the formula

$d=2r\rightarrow d=2(12)=24$
