I need some help in this
The question states find the volume for the region bounded below by z = 3 - 2y and above by z = x^2 + y^2 using cylindrical coordinates .
Now i tried to do it but i got stuck with the part where i find the radius . i found
r^2 = 3-2r*sin(zeta) :( its hard to factorize and use this for the boundary
i already know that z will range from r^2 to 3-2r*sin(zeta) and zeta range from zero to 2 pie
so how can this question be solved ? :)
btw the correct answer is 8pie
