Question

A can is 15 centimeters tall and has a diameter of 7.5 centimeters. It fits into a rubberized cylindrical holder that is 13.5 centimeters tall, including 1 centimeter, which is the thickness of the base of the holder. The empty space used to keep the can has a radius of 3 cm and the thickness of the rim of the holder is 1 centimeter. What is the volume of the rubberized material that makes up the holder?

Answer 1

324.99 cm³

Explanation:

Total volume - inside volume

[pi × (3+1)² × (13.5)] - [pi × 3² × (13.5-1)]

216pi - 112.5pi

110.5pi

103.5 × 3.14

324.99 cm³
