Question

A hotel swimming pool is made up of four semicircles and a square. Find the perimeter of the swimming pool. Round your answer to the nearest tenth. 10 yd 10 yd 10 yd 10 yd​

Answer 1

62.8yd

Explanation:

formula for circumference of a circle = 2 π r

The perimeter is 4 semi circles, so 2 full circles. The diameter is 10yd and the radius is half the diameter, so the radius is 5yd

working:

2 x π x 5 = 31.4yd

31.4 x 2 = 62.8yd
