Learn about the surface area and volume of a cylinder with this BBC Bitesize Maths article. For students between the ages of 11 and 14.

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together.

The goal of 21st-century cylinder head engineering is controlling and managing the combustion process by combining radical combustion chambers with new port layouts to improve mixture motion.
