Question

The area of circle is 55.44m square. Find it's radius​

Answer 1

area of circle =

2

55.44=22/7×r^2

55.44×7/22=r^2

2.52×7/2=r^2

r=_/17.64

r= 4.2

Answer 2

Answer:

Given: Area of square = 55.44m square

Let the radius be 'r'.

We know that -

Area of circle = πr^2

55.44m sqaure = πr^2

=> 55.44π = r^2

=> 55.44×7/22 = r^2

=> 17.64 = r^2

=> √17.64 = r

=> 4.2 = r

Hence, the radius of the circle will be 13.2m.

( Note : Here the value of radius may vary if in the question the value of π given to us will be 3.14 )
