The question reads, "Find the dimensions of a cylindrical tennis ball container which has the volume of V(x)=8πx3+17πx2+10πx+π such that the volume is exactly 825π cm3. Hint: V = πr2h." To start off, I set V(x)=825π and moved it to the right side, giving 0 = 8πx3+17πx2+10πx-824π. Factoring pi, we get 0 = π(x-4)(8x2+49x+206), Since we can't factor the second bracket, here's where I get confused. My inference is that the radius is 4 cm, and the height is muzzled in that unfactorable bracket. However, having the equation for volume (V = πr2h), I get h = 825/16π. Can someone verify this for me, please?
