Answer:

Circumference of circle = 31.42 ft.

Step-by-step explanation:

Given the following data;

Area of circle = 25π ft²

To find the circumference of the circle;

First of all, we would determine the value of its radius;

Area of circle =πr²

25π = πr²

r² = 25

Taking the square root of both sides, we have;

r = 5 ft.

Now, to find its circumference;

Circumference of circle = 2πr

Circumference of circle = 2π*5

Circumference of circle = 10π ft.

π = 3.142

10π = 10 * 3.142 = 31.42

Circumference of circle = 31.42 ft.
