Consider the inverted paraboloid defined by the equation $\displaystyle z = 10 - 2(x^2 + y^2)$. Under this area but above the x-y plane is a cylinder whose axis lies along the z-axis and whose radius is a = 2.00cm. We wish to consider the part of this cylinder that extends from the x-y plane up to the height where it intersects the paraboloid.

a) How tall is the cylinder under the paraboloid?

b) Consider the cylinderplusits parabolic cap (the part of the paraboloid cut out by the cylinder). What is the surface area of this curved cap?

c) What is the entire volume contained within the cylinder, from above the x-y plane to just below the cap?

d) The y-z plane cuts through the cylinder and its parabolic cap. What is the length of the parabolic arc formed by the cross section (that is cut out by the y-z plane) of the parabolic cap above the cylinder?

Just some starting tips or hints would be great...
