area of the base

= area of the circle with radius 8

= π(8^2) = 64π units

Volume = (1/3)πr^2 h

= (1/3)π(64)(17) = 544π units^2

these are the answer I have to pick from for volume

1088/3 pi feet cubed

960 pi feet cubed

320 pi feet cubed

1088 pi feet cubed

You could have easily seen that I made a calculation error

(1/3)π(64)(17) is correct,

but then I must have divided by 2 instead of by 3

clearly it should have been

10880π/3
