Question

Can you help me with this question? ​

Answer 1

12.8 cm

Explanation:

So let's find the volume fo the can of paint.

The formula for volume of a cylinder is
`\pi`r^2 h.

Plugging the height and radius in, we get

`\pi`64*20

or
`\pi`1280

Since Jamil has 1/4 of a can of paint remaining, we multiply the volume by 1/4 to get:

320
`\pi`

Since the smaller can has to have a volume of 320
`\pi`,

we divide it by 25 to get
`\pi`h or 12.8
`\pi`

So the height of the smaller can is 12.8 cm
