Unfortunately I do not know the rectangle you are speaking of, if you could provide the rectangle I would be happy to help.
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

4.5x67=301.7
6/5x78=63.6
20-100+3000=2920
Answer:
