  • I need to add murridic acid to my pool. If my pool is 21ft by 4 feet high, how many gallons of water are in it?

  • Answer:

    4 * p i* r^2 = pi * 10.5 * 10.5 *4 = 1385.44236023309881 cubic feet 1385.44236023309881 cubic feet = 10,363.8285 US gallons Also remember your pool may be 4ft deep but you usually dont fill it all the way to the top.

pi r squared or pi10.5 squared times 4 gives you volume in cubic feet,,,,then you need to find a cubic foot to gallon multiplier,,,you have all the dimensions you need,,,monkeys are smarter than the humans who have answered so far
