A half filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the diameter of the tank in feet to the nearest tenth

Answer 1

V = pi x r² x h

r² = V / (pi x h)

r = √ V / (pi x h)

r = √ 6000 / (3.14 x 20)

r = 9.77

d = 2r, so d = 2 x 9.77 = 19.5 ft
