Question

The circumference of a circle is 10π ft. What is the area, in square feet? Express your answer in terms of \piπ.

Answer 1

Answer:

A = 25π square feet

Step-by-step explanation:

C = 2πr

10π = 2πr

10π = 2πx

10π / 2π = 2πx / 2π

5 = x

This means 5 is the radius of the circle. We now need to find the area:

A = πr$r^{2}$

A = π(5)²

A = π(25)

A = 25π
