Sirgeo wants to fence in a circular portion of his backyard for a place space for his dog. Determine the area of the largest portion of the yard he can close with 72 feet of fencing use 3.14 for pi

  412.7 square feet

Step-by-step explanation:

A circle of circumference 72 ft will have a radius given by ...

  C = 2πr

  (72 ft) = 2(3.14)r

  r = (72 ft)/(6.28) ≈ 11.465 ft

The area of a circle with that radius is ...

  A = πr² = 3.14(11.465 ft)² ≈ 412.7 ft²

Sirgeo can enclose a circular area of about 412.7 square feet with 72 feet of fence.
