8-40.

Suppose you were to bend two whole sheets of 8 1/2-by-11 paper to form two cylinders (a tall, skinny one and a short, wide one). The volume of a cylinder can be calculated using the formula*V*= (*base area*)(*height*) or*V*=*πr*^{2}*h*. Homework Help ✎Do the two cylinders have the same volume?

**Justify**your answer.Is the result different if you start with

-by- paper?

Calculate the volume of both cylinders and compare.

Remember, for cylinders:*V* = π*r*^{2}*h**C* = 2π*r*

Where *V* is volume, *r* is radius, *h* is height, and *C* is circumference.

For the tall cylinder:

*V* ≈ 63.24 in.^{3}
