# Thread: volume and calculus for upcoiming exam!

1. ## volume and calculus for upcoiming exam!

Hi,Would really appreciate help with text in red.thanks.
one of the question asks for region of integration and evaluation of e^(2x+y)dydx where inner integral goes from x to 3x;outer integral froom o to 4.
but I have issues with this part:-how should I solve?
the solid sphere x^2+y^2+z^2 is less than or equal R^2 has a hole bored through it by the solid vertical cylinder x^2+y^2 less than or equal to Q^2 where
0<Q<R.
calculate volume of part of the sphere that is removed.
