Question

Find the volume of the solid bound between the paraboloid z = x^2 + y^2 and the plane x + z = 0
as follows.
(a) Find an equation describing the projection of the intersection of the plane and the paraboloid in the
xy-plane. What is the shape of the curve described by the equation?
(Hint: find a relation between x and y using the two equations, then complete the square to identify the shape
of the curve.)
(b) Rewrite the equation from part (a) as a polar equation.
(c) Using your answer from part (b), compute the volume using a triple integral in cylindrical coordinates.
