Uses of π
Volume of a Cylinder
When dealing with 3-D solids, we have volume, total area and lateral area. In order to understand these completely, we have included the following definitions.
Volume - The amount of 3-D space an object takes up
Lateral area - Surface area of an object not including the bases
Total area - Lateral area plus the area of the bases
You have a cylinder with a radius of 3.14 cm and a height of 7.2 cm. Find the lateral area, total area, and volume.
Take the knowns (r=3.14 and h=7.2) and plug them into the equations.
S=45.21pi or approximately 142
T=64.93pi or 204
V=71 pi or 223
