To answer this, we need to use the equation for the volume of a cylinder:
Where:
'V' : Volume
'r' : radius
'h' : height
Now we plug in our values and solve:
V = <span>13571.68 cubic feet
</span>
∴Despite not being exactly what we got, the answer must be 'B'. It is the closest value to our solution without going over.
