A roll of paper towels has a radius of 12 cm and a height of 18 cm. the cardboard tube in the centre has a radius of 5cm.

Find the volume of the paper towels

So would I do 18-12?

1 answer

why ever would you subtract radius from height?

The volume of towels is the volume of the whole package, minus the volume of the inner cylinder. Recall that the volume of a cylinder is v = πr^2 h. So, the volume of the towels is

π*12^2*18 - π*5^2*18 = 2142π cm^3
