Question

what is the volume of a rainwater collection tank that is shaped like a cylinder with a diameter of 10 cm when using 3.14 for
`\pi`

Answer 1

The equation to find the volume of a cylinder is V=
`\pi`×r²×h. To find r you just divide the diameter which is 10 by 2 so r is 5. Just plug everything in and solve, V=
`\pi`×5²×243.84. You should get V≈19,151.15
