Question

PLEASE HELP

A cylinder-shaped container is used to store water. The container has a height of 6 feet and
diameter of 3 feet.
About how much water is in the container when it is 3/4 full?

o 127 cubic feet
o 42 cubic feet
o 32 cubic feet
o 14 cubic feet

Answer 1

32 cubic feet

Explanation:

The formula for a cylinder is
`\pi r^(2) h`.

The radius of the cylinder is equal to 1.5 feet, since it is
`(diameter)/(2)`.

Plugging in, the cylinder's full volume is
`6\pi 1.5^2` which is approximately 42.4 cubic feet.

To find the amount of water when it is 3/4 full, multiply 42.4 x .75, to get around 31.8, and 32 when rounded
