The area of a circular swimming pool is 225pi square meters. What is the circumference of the swimming pool? Leave your answer in terms of pi.

The square root of 225 is 15. Therefore, the diameter must be 30

C = 30pi

To find the circumference of a circular swimming pool, we can use the formula C = 2πr, where C represents the circumference and r represents the radius of the circle.

First, we need to find the radius of the swimming pool. We know that the area of the swimming pool is 225π square meters. The formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius.

So, we can rearrange the formula and solve for r:
A = πr^2
225π = πr^2

Dividing both sides of the equation by π:
225 = r^2

Next, we need to find the square root of both sides to solve for r:
√225 = √r^2
15 = r

Now that we have the radius, we can substitute this value into the formula for the circumference of a circle:
C = 2πr
C = 2π(15)
C = 30π

Therefore, the circumference of the swimming pool is 30π meters.
