Question

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)?

Answer 1

we need circumfrencee, and the formula for that is pi times diameter.
circumfrence comes to 35 x3.141
that comes to 109.96 ft, more or less. lets round to 110 to keep our live simple.
$12.50 for every foot, and we need 110 feet of fence.
12.50 x 110 = $1375.
very expensive fence
