The fountain is made up of two semicircles and a quarter circle. find the area of the fountain. round the area to the nearest square foot.

Radius of semi circles is 10 ft.

Area of semi circle is half the area of a normal circle.

Area of two semicircles: 1/2 * pi r^2 + 1/2 * pi r^2  = pi * r^2

So area of two semicircles with radius 10 ft = pi * 10^2 = 100 pi 

Area of qtr circle: is quarter the area of a normal circle

Area of a quarter circle: 1/4 * pi r ^2

quarter circle has radius of 20 ft so area of it is 1/4 * pi * 20^2 = 100 pi

Total area = area of two semi + area of quarter
= 100pi + 100pi
= 200pi
≈ 628 ft²
