A bottle of lotion is shaped like a cylinder with a radius of 3 cm and a height of 12 cm. The empty tube inside the cylinder has a radius of 0.5 cm and is the same height as the bottle.

What is the volume of the lotion in the bottle? Use 3.14 to approximate pi, and express your answer to one decimal place.

V = pi * r^2 * h

V = 3.14 * 3^2 * 12

V = 339.12

This is the volume of the bottle of lotion, now let's find the volume of the empty tube inside, then we can subtract that from the total volume of the bottle of lotion.

V = pi * r^2 * h

V = 3.14 * 0.5^2 * 12

V = 9.42

This is the volume of the empty space inside the lotion, now subtract it from the total:

339.12 - 9.42 = 329.7

So the volume of the lotion inside the bottle is 329.7.
