1. The problem statement, all variables and given/known data find the volume of the ellipsoid x^2+y^2+5z^2=16 3. The attempt at a solution so I assume I must first change it to spherical coordinates. I figure I evaluate θ from 0 to 2∏ abd ∅ from 0 to ∏, but the p is giving me a challenge. if z is zero then p goes from 0 to 4, but if x and y are zero then p goes from 0 to (16/5)^(1/2)? am I on the right track? What do I do now??
