Homework Statement
A volume is enclosed by the plane z = 0 and the inverted paraboloid, z = 6 − r2 (expressed in cylindrical coordinates). Find the volume and its surface area.
Hence, using a suitable linear transformation, find the volume of the region enclosed between the surfaces z = ax^2 +by^2 and z = 6−cx^2 −dy^2 where a, b, c and d are positive constants

The Attempt at a Solution
So I've managed to do the first part (Photo of my working will be below), but am now struggling to calculate the volume between the two paraboloids. I thought of one possible parameterisation in which u^2=b/a x^2 and v^2=d/c x^2 so that I transform the two elliptical paraboloids into regular ones, but this would mean I have a 4-dimentional coordinate system, which is obviously not correct. Its mainly the parameterisation I'm struggling with
Many thanks in advance :)
