What is the exact volume of the cylinder?
height= 8 inches
radius= 4 inches

32π in³

64π in³

128π in³

512π in³

The formula for a cylinder is πr²*h where r is the radius and h is the height:

1.) Plug in r for 4, as the radius is 4
π(4)²*h

2.) Plug in h for 8, as the height is 8
π(4)²*8

3.) Simplify 4²
π(16)8

4.) Simplify 16*8
π128

5.) Don't forget your units, inches cubed (because you multiplied three dimensions all with inches, which results in the inches being multiplied three times as well)
π128 in³ or 128πin³

It is the third answer choice, hope this helped :)

The best estimate would be about 1 foot
