Question

If the circumference of a circle is 10π inches, what is the area, in square inches, of the circle?

Answer 1

25π square inches or 78.5 sq in

Explanation:

circumference = π x diameter

thus

10 π inches= π x d

d = 10 inches

area of circle = π x d x d / 4

= π x 10 x 10 x 4

= 25π sq in

= 78.5 sq in
