Question

A) If the perimeter of a circle is 44 cm,
(i) find its radius.
(ii) find its area.​

Answer 1

`154 \: {cm}^(2)`

Explanation:

Let the radius be = r cm

circumference = 2πr

`44 = 2 * (22)/(7 ) * r`

`r = (44 * 7)/(44) * 7`

`r = 7 \: cm`

Area of circle =

`\pi {r}^(2)`

`= (22)/(7) * 7 * 7`

`= {154 \: cm}^(2)`
