Each of the following integrals represents the volume of either a
hemisphere or a cone, and the variable of integration measures a
length. In each case, say which shape is represented and give the
radius of the hemisphere or radius and height of the cone.
*Make a sketch of the region, showing the slice used to find
the integral, labeling the variable and differential on your
sketch.* Then evaluate the integral to find the area.

**A.**

Which is the shape of the region being integrated?
** A. ** Cone** B. ** Hemisphere

radius/radius and height =

*(Enter the radius, or the radius and height separated by a
comma, e.g.,* **4, 3***)*

volume =
