Question

The radius of a circle is 10 ft. Find its area in terms of π π.

Answer 1

area of circle : πr^2

= π(10)^2

= 314.1592654

≈ 314.16 cm2

Answer 2

100π sq. ft

Explanation:

Given,

Radius ( r ) = 10 ft

To find : Area ( circle ) = ?

Formula : -

Area ( circle ) = π r^2

Area ( circle )

= π x 10^2

= π x 100

= 100π sq. ft
