Question

a round clock on a classroom wall has a diameter of 12 inches. what the approximate area of the clock?

Answer 1

a=π6²
a=π36
area≈101.1 or 101.097

Answer 2

113.1

Explanation:

To calculate the area of a circle the formula used is A= π r²

Where A is the area, π is 3.1416 and r is the radius. Whe know that the diameter is two times the radius, therefore we divide 12/2 to obtain a radius of 6 inches and now we proceed to use the formula in the beginning:

A= π r²

A=( 3.1416) (6²)

A=(3.1416)(36) =113.1
