Answer:
12.8 cm
Explanation:
So let's find the volume fo the can of paint.
The formula for volume of a cylinder is
r^2 h.
Plugging the height and radius in, we get
64*20
or
1280
Since Jamil has 1/4 of a can of paint remaining, we multiply the volume by 1/4 to get:
320

Since the smaller can has to have a volume of 320
,
we divide it by 25 to get
h or 12.8

So the height of the smaller can is 12.8 cm
