Question

Find the area of the semicircle of 35 inches

Answer 1

the area is 1016.575
because the formula for area is radius times radius times pie
(35 divided by 2 is the radius which is 17.5, 17.5 times 17.5 is 306.25, times pie is 1016.575)
hope it helped :)

Answer 2

A = 1/2 πr^2 = 1/2 π (17.5)^2
A = 306.25 / 2 π
A = 153.125 π in^2

answer A = 153.125 π in^2
