Area and Volume of a PearDate: 6/4/96 at 0:4:16 From: Anonymous Subject: Area and Volume of a Pear How do you find the area and volume of a pear?? Date: 6/5/96 at 17:5:55 From: Doctor Ceeks Subject: Re: Area and Volume of a Pear The following method will give you a pretty good answer: For volume: Take a bucket of water. Immerse your pear in the bucket so it is completely covered. (You can use a teriyaki stick to keep the pear under.) Observe the change in water level. This tells you how much water is displaced by the pear, and since water is incompressible, you can get the volume. For area: This is somewhat harder to pull off. Take a bucket of chocolate syrup. Dunk your pear in the bucket so as to completely cover the pear with chocolate. Pull it out. Let it drip until it doesn't drip anymore. Figure out how much chocolate syrup it took to cover the pear by measuring the difference in the amount of syrup in the bucket before and after. The surface area of the pear is roughly proportional to this amount. To determine the constant of proportionality, perform the same procedure with a sphere of known surface area (use the formula 4*pi*r^2, where r is the radius of the sphere). Important: Do not eat pear until after final measurements have been taken. There are many other ways however, so see if you can find another. -Doctor Ceeks, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
