    -Volume-

    Volume the solid limited by surfaces x^2+y^2=4z , x^2+y^2=8y and z=0

    Is correct?
    V=2\int_{0}^{\frac{\pi}{2}} \int_{0}^{8sen\theta} \int_{0}^{\frac{P^2}{4}}

    to be mounted in cylindrical coordinates?

    The answer is:
    256\pi

    You're on the right track it would appear.

    \int_{0}^{2\pi}\int_{0}^{8sin{\theta}}\int_{0}^{8}  r \;\ dzdrd{\theta}
