**Teacher:** |
**Well, that probably answers the next
question, too. All right?** |

**Student2:** |
**Yeah, if you get down to point-zero-two,
or something...** |

**Teacher:** |
**But what I did is I graphed it on
my calculator, and looked at the graph** |

**Student2:** |
**If it looked like it would
get really close and be one of those ones...** |

**Teacher:** |
**I have a question, and this is probably
more than I should give you.** |

**Teacher:** |
**But, what if we graphed the volume
function? ** |

**Teacher:** |
**If i'm telling you the volume function,
so, volume is what, 2-pi-r. ** |

**Teacher:** |
**No, it's pi-r-squared-h, right? I
can only have one letter. ** |

**Teacher:** |
**Is there a way you can get that with
an r in it? Instead of using h?** |

**Student1:** |
**No.** |

**Teacher:** |
**Oh, I think there may be. Here's
your ... and it's 93.5 and this is 2-y-r and this is h.** |

**Student1:** |
**Well, you can divide this...** |
