Puzzle #50: Making a round based solid

If you have a rectangle 1ft.x2ft., you can make a round based solid by rotating the rectangle about the 1ft. side or the 2ft. side.

But do they make the same size solid?

Hint: Recall the volume of a round base solid is the area of the round base (circle) times the height, where the area of a circle is 2pi(r²).
