Question

What is the area of the shot put circle whose radius is 2.135 metre what is the diameter calculating area formula explanation

Answer 1

Step-by-step explanation:

Given Calculate the area of the shot put circle whose radius is 2.1 35 metre

We need to calculate the area of a shot put circle.

So we know that Area of a circle is π r^2  

r is the radius of the circle.

r = 2.135 m

Value of π is 22/7

So area of circle

                       = 22/7 x (2.135 )^2

                      =  22/7 x 2.135 x 2.135

                      = 100.28095 / 7

                    Area  = 14.32585 sq m

We know that diameter = 2 x r

                                       = 2 x 2.135  

                                       = 4.27 m
