17. A block of lead in the form of a right prism is 10 inches long and has trapezoidal bases. The trapezoid has parallel sides of lengths 2 in and 4 in, and an altitude of 3 in. The block is melted then transformed into a 9 inch-long right circular cylinder. No material was lost in the process. Req'd: 1. Draw the two figures (before and after the transformation). 2. Solve for the radius of the cylinder. 3. Solve for the surface area of the cylinder.
