Answer:
The answer is 9x8 (C)
Step-by-step explanation:
The volume of the cylinder is πr2h
So we have ,
Height:11.5in
Diameter:8.5in
Radius=8.5/2
Now from the above information,
Volume = πr2h
= 22/7x8.5/2x8.5/2x11.5
Cancelling 2and 22 ,we get,
=11/7x8.5x4.25x11.5 (as we divided 8.5/2)
=1.57x8.5x4.25x11.5
=652.2in3
HOPE IT WAS HELPFUL :)
