Estimate the area of a circle with a radius of 21 meters. use start fraction 22 over 7 end fraction for pi. i need the answer for this writing question! ?

Area of the circle with a radius of 12 meter is  1386 .

Step-by-step explanation:

Given :

Radius of a circle = 21 meter.

pi (π) = 22 over 7

To find :

                   Estimate the area of a circle.

Formula used :

                     Area of the circle = π ×.

Explanation : We are given that

                                 Radius of the circle = 21 meter.

                                       pi (π) =

Plugging the given values in above formula,

                            Area of the circle = ×.

On simplification we get,

                             Area of the circle = 1386 .

Therefore, Area of the circle with a radius of 12 meter is  1386 .
