Hi, I am a Maple newbie. My problem is I do not know how to generate the result to find the answers of these question: 

1. a)   Sketch the surface area of the part of paraboloid z = x² + y² that lies under the plane z=8.

b)   Compute the surface area.

2. a)   Sketch the solid that lies above the cone z = (x² + y²)^1/2 and inside the sphere x² + y² + z² = 16.

b)   Compute the volume of the solid.

It is possible to calculate these question? Does anyone has a suggestion? Thank you.
