Answer:
34,833.21 ft³
Step-by-step explanation:
Volume of a cylinder = πr²h
r is the radius
h is the height
Given
height h = 19 3/4 ft
d = 1 1/5h
d = 6/5 * h
d = 6/5 * 19 3/4
d = 6/5 * 79/4
d = 474/20
radius r = 474/20 * 1/2
radius r = 474/40
radus r = 11 34/40
radus r = 11 17/20 ft
Get the volume
V = 3.14 * (474/40)² * 79/4
V = 3.14 * 561.69 * 19.75
V = 34,833.20535
Hence the volume of the cylinder to the nearest hundredth is 34,833.21 ft³
