1. The problem statement, all variables and given/known data determine the volume of the solid S which is bounded above by the surface z=10-x^2 and below by the z=Y^2+1; 2. Relevant equations 3. The attempt at a solution what i did was first i tried to find the intersecting points of two surfaces .So i equal two functions and i got x^2+y^2=9 which is a circle center (0,0) and radius 3.then i used polar coordinates to evaluate this . (r goes from 0 to 3 and theta goes from 0 to 2*pi )integrate (9-x^2-y^2)drd@. am i correct ??or have i mad any kind of error?please explain????
