Find the volume of the solid in R^3 above the plane z = 0 and below the surface z = 4 − x^2 − y^2.
The given surface is,
put z = 0,
Hence the given region D is the circle with radius 2 in XY plane,
The volume of the solid is given by,
using polar coordinates as follows,
Now the integral in polar becomes,
integrate wrt r,
integrate wrt theta,
