Answer: 18x 45 58 should be correct
15184.6
V = pi x r^ 2
H = pi x 13^2 x 28.6
Note that this just produces three parametric equations:
In the
plane, this is just he parametric equation for an ellipse (as a function of u). The z is simply a linear function.
The surface is then an ellipse extruded along the z-axis. We get a elliptic cylinder.
