What is the significance of π in volume calculations?

Back

π (pi) is a constant approximately equal to 3.14, used in calculations involving circles, such as the base of a cylinder.

Front

If the height of a cylinder is doubled, how does that affect the volume?

Back

Doubling the height of a cylinder will double its volume, assuming the radius remains the same.
