A fountain is made up of two semicircles and a quarter circle. The diameter of the semicircles is 10ft. Find the perimeter of the fountain. Round your answer to the nearest tenth.
Assuming the quarter circle has the same diameter as the semi-circles, we have
pi[10ft] +[ pi/4][10ft] = [5/4]pi(10 ft] = [50/4]pi ft = [25/2]pi ft = 12.5 pi ft = about 39.27 ft
