SURFACE AREA AND VOLUME OF SPHERE
Performance Objectives
Student should be able to:
- Calculate the volume and surface are of a sphere
- Calculate the volume and surface area of the hemisphere
Content
Surface Area and Volume of Solids
Before we talk about the sphere and the hemisphere it is important we refresh our memory on the formulae for the surface area and volume of some common solid

1. |
Cube |
Volume=l×l×l |
|
|
|
Surface area =6×l×l |
|
|

2. |
Cuboid |
Volume=lbh |
|
|
|
Surface area =2(lb+lh+bh) |
|
|
|
Curved surface area = πrl |
|
|
|
Total surface area = πrl+πr2 |
