Question

Find the area of circle of radius 30cm ( use the pai 22\7

Answer 1

we know that area of circle is pi(r)^2
by this 22/7×30×30 is equnlikely to 2828.57square centimeters

Answer 2

radius = 30cm

area of circle = πr²

                      =22/7*30²

                      = 22/7*900

                      = 2828 .571428
