Question

Anita has a string of lights that is 30 ft long if she makes a complete circle with these lights what is the approximate radius of the largest Circle she can make​

Answer 1

radius ≈ 4.75 ft

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
