Answer:
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.
