Actually the first step in the calculation is incorrect. If the pool is 27' and they want a 2-1/2' border all the way around, the the total circle would be 27+2.5+2.5 = 32'

All great except there are 27 cubic feet in one cubic yard, not 9.

I can help with math through algebra and geometry -- not trig and not calculus. I can help with fractions, percents, decimals, using other bases, word problems, etc.


I majored in math in high school and have scored very high on standardized tests.
