So if I double the velocity, aerodynamic drag doubles as well?

Sorry, forgot to mention it's revolving around the x-axis. Anyways, I got this from a friend pi * Int[0,pi/4] (cosx)^2 - (sinx)^2 dx), and I was wondering where the lower boundary, 0, came from.

Find the volume of the solid y = sinx, y=cosx, and x= pi/4, revolving around x-axis I didn't really get this at all... do I plug pi/4 for x in y=sinx, y=cosx to get the integra boundaries?
