Question

Find the area of the shaded region, assume a = 49 in. (Assume that given measurements are exact, and round approximate answers to the nearest tenth of a square unit.)

Answer 1

a = pi r^2

The diameter = 49 inches. The radius = 24.5

a = pi times 24.5^2

1885.7 square inches

Answer 2

I do that but am not getting the same answer i get 1884.7

Answer 3

Did you use 3.14 or did you use the pi key?

Answer 4
