Let us learn what is a radius?
The space from the center to the edge of a circle
it is 1/2 of the circle's diameter is called radius
it is 1/2 of the circle's diameter is called radius
Find the diameter of the circle whose area is 22cm.
Solution:
Given that the area of the circle is 22cm.
Area of the circle = pi *r2
22 = pi * r2
22 = 3.14 * r2
Divide by 3.14 on both sides
22/3.14 = 3.14 * r2/3.14
71.66 = r2
r = √7.01
r = 2.65cm.
Diameter of a circle = 2 * radius
= 2 * 2.65
=5.3cm.
