If the diameter is 35' then we can use the the circumference formula to find the total length around the outside of the pool:

\(A= \pi d = (3.14)(35') = 109.9'\)

We can then use this length and the unit rate price to find the total cost:

[tex]C=Length * Unit Price = (109.9')($12.50/ft) = $1373.75
