|| h=8 Let this picture or model represent a cylinder. v=πr2h. v= π( 4 )2 * 8 Use substitution.
∅ d=8 If d=8, then r=(1/2)d=4 Change pi to 3.14 or 22/7
⁄___⁄| Note: All sides of a cube are equal. L=8, w=8, and h=8 V=L*W*H Use substitution.
|__|⁄ Multiply all dimensions together.
Finally, just find the volume for each and compare which has the greater volume.
I hope that this example helps. Susan C.
