Question

The circumference of a circle is 26 pi what is the area in square inches of the circle

Answer 1

circumference=

`2\pi \: radius`

`26\pi = 2\pi \: raduis \:`

`(26\pi)/(2\pi) = raduis`

radius = 13

area of circle =

`\pi {raduis}^(2)`

area of circle=

`\pi {13}^(2)`

area of circle=

`169\pi`
