Question

Find the area of a circle whose circumference is same as the perimeter of square of side 22 cm

Answer 1

Perimeter of square = 4(Side)

Given, side = 22cm.

So.. 4(22) =88

Circumference of circle =2^r

So, 2^r = 88 ( because given that circumference is same as perimeter)

2(22/7)(r) = 88

44/7 (r) = 88

r =88(7)/44

r=616/44

r=14

So, area of circle = ^ rsquare

= 22/7 (14)(14)

22/7 (186)
