I understand how to do solid revolution problems, but I keep ending up with decimals when it says it shouldn't.
The problem is below. Also, the answer I got is 9057.13.
The region bounded by f(x)= −4x^2+20x+56 , x=0 y=0 is rotated about the y-axis. Find the volume of the solid of revolution.
Find the exact value; write answer without decimals.
