Find the volume of the body of revolution formed by the ellipse x ^ 2 / 9 + y ^ 2 / 4 = 1 rotating around the X axis Need process! Urgent!
Ellipsoid volume v = ∫ s (z) DZ = ∫ π * a * b * (1-z ^ 2 / C ^ 2) DZ = 4 / 3 * π * a * b * C
Ellipsoid surface area s = 4 π (AB + BC + AC) / 3
I think it's ok if the formula is here
