The fountain is made up of two semicircles and a quarter circle. find the perimeter and the area of the fountain. round the perimeter to the nearest tenth of a foot and the area to the nearest square foot. both have the diameter 20

The perimeter of the fountain = 94.2 ft

The area of the fountain = 628 ft²

Given:

Diameter of the semicircle = 20 ft

Therefore, Radius (r) = half of diameter = 10 ft

Radius of the quarter circle = 20 ft

Perimeter of the fountain = ½(2πr) + ½(2πr) + ¼(2πr)

Perimeter of the fountain = ½(2π(10)) + ½(2π(10)) + ¼(2π(20))

Perimeter of the fountain = 94.2 ft

Area of the fountain = 2(½(πr²)) + ¼(πr²)

Area of the fountain = 2(½(π10²)) + ¼(π20²)

Area of the fountain = 628 ft²
