CYLINDER

Cylinder












Definition


Is a three-dimensional geometric shape
It has a flat base and a flat top
The base is the same as the top, and also in-between
It has one curved side
Because it has a curved surface it is not a polyhedron.







AREA

Surface Area = 2 × π × r × (r+h)


VOLUME

Area of the circle: π × r^2

Height: h

Volume = Area × Height = π × r^2 × h
