Question

A cylindrical barrel has a radius of 7.6 ft. and a height of 10.8 ft. Tripling which dimensions will triple the volume of the barrel?

Answer 1

tripling the height will triple the volume.

Formua is r^2 *
`\pi` * height.

If you triple the radius, you must still square it, so it will be 9 times bigger.

If you triple the height, then it will be 3 times bigger.
