**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.**
