Answer:

about 0.35 inches

Explanation:

You want to know the difference between the circumference and height of a can that holds three balls that are 2.5 inches in diameter.

Circumference

The circumference is given by the equation ...

C = πd

For a 2.5 inch diameter, the circumference is ...

C = π(2.5 in) = 2.5π in

Height

The height of the can that holds three balls of diameter 2.5 in is ...

h = 3(2.5 in)

Difference

The difference of interest is ...

C -h = 2.5π in - 2.5(3) in = 2.5(π -3) in = 2.5(0.14) in = 0.35 in

The circumference is about 0.35 inches more than the height.
