The surface area of a sphere can be calculated using the following formula, where r is the radius of the sphere
The volume of a sphere can be calcuated using the following formula, where r is the radius of the sphere
In order to compare the surfrace area and volume of a sphere, we are going to look differnt radius values of balls.
Type of Ball | Radius (in inches) |
Ping-pong Ball | 0.74 |
Golf Ball | 0.84 |
Billard Ball | 1.13 |
Tennis Ball | 1.26 |
Baseball | 1.47 |
Bowling Ball | 4.29 |
Basketball | 4.72 |
Calculate the surface area and volume for the above spheres, using Microsoft Excel. Next, use your graphing tool to graph the surface area and volume on the same axis.
