Answer:

Step-by-step explanation:
Volume of a cylinder is given by cross sectional area multiplied by height hence
V=Ah
Since the cross sectional area of

Substituting the formula for A into formula for volume then

Substituting 8ft for r and 20 ft for h then

Rounded off to the nearest tenths, the volume is equivalent to
