Answer:
radius ≈ 4.75 ft
Step-by-step explanation:
The circumference of a circle is the perimeter of a circle, or the outside measure of a circle. With the amount of lights Anita has, the largest circumference of a circle she can make is 30 ft. The formula for circumference is: C = 2πr, where 'r' = radius.
Filling in the maximum measure:
30 = 2πr or 15 = πr
Divide by π on both sides: 15/π = πr/π or r ≈ 4.75ft
