How much will it cost to fence a circular swimming pool at the edge of the pool if it has a diameter of 35 feet and fencing costs $12.50 per foot (use = 3.14)?

a. $8.79

b. $437.50

c. $1,373.75

d. $1,923.25

Diameter of the pool that needs to be fenced = 35 feet
Radius of the pool that needs to be fenced = (35/2) feet
                                                                     = 17.5 feet
Circumference of the circular pool = 2 * pi * radius
                                                       = 2 * 3.14 * 17.5 
                                                       = 109.9 feet
Cost of fencing = 109.9 * 12.50 dollar
                         = 1373.75 dollars
From the above deduction it can be concluded that the correct option is option "C".
