A circular fountain has a radius of 30 feet. Which expression an be used to find the circumference of the fountain, in feet?

Answer 1

The expression that can be used to find the circumference of the fountain, in feet, is:

C = 2πr

where C represents the circumference and r represents the radius.

In this case, the expression would be:

C = 2π(30)

C = 60π

Therefore, the expression to find the circumference of the fountain is 60π feet.
