Pool Volume

What could be so hard. It's a multiple-choice test for Pete's sake.

Pool Volume

Postby Calculus98 » Sat Mar 09, 2013 4:03 pm

On most of the tests I have taken recently there has been a question like:

"Joe built a pool that is circular in shape and is a constant of five feet deep. If the diameter if the pool is 28 feet, find the amount of water required to completely fill the pool. ( nearest whole gallon)"

How would you solve this?

It's a unit conversion. You have a cylinder so find the volume in ft^3, then convert to gallons, knowing that 1ft^3 is approximately 7.48 gallons.

You would use the conversion 231 cubic inches equals one gallon for more accurate results. Otherwise, do what he said.
Now I know the stakes, and I'm willing to show what I gots. I will see you all at state for the first and final time, so let's end the year with a bang! :)
