Cylinders
By: Will Davies, Remi Andre, Paul Carothers, and Blair Dodson
The definition of a cylinder: A surface or solid bounded by two parallel planes and generated by a straight line moving parallel to the given planes and tracing a curve bounded by the planes and lying in a plane perpendicular or oblique to the given planes.
Formulas for cylinders: Volume= Area of base × height = pi × r2× h

Use 3.14 for pi.

Notice that the base of the cylinder is a circle and the formula to get the are is pi × r2

Example #1:

Calculate Volume cylinder if r = 2 cm and h = 5 cm

Volumecylinder = pi × r2× h

Volumecylinder = 3.14 × 22× 5

Volumecylinder = 3.14 × 4 × 5

Volumecylinder = 3.14 × 20

Volumecylinder = 62.8 cm3

Example #2:

Calculate Volumec ylinder if r = 4 inches and h = 8 inches
