Question

Area of circle is 176sqcm . Diameter ?

Answer 1

This is a intermediate level Qn kiddo,

To Answer this, you must know :

i) Area = πr^2

ii) Diameter = 2 r

where r is the radius , so let's move on to the problem.

Given area is 176 sq.m

That is

πr^2 = 176

r^2 = 176/3.14

= 56.05

r = sqrt of 56.05

= 7.48( approximately)

We got radius as 7.84 m.

So diameter is 2* 7.84

= 15.68
