The question gives you the circumference (C in the formula), and you need to find the radius (r in the formula). Begin by isolating r in the circumference formula.
C = 2πr C/2π = r r = C/2π
Now you can plug 96 for C and solve to find r.
r = C/2π r = 96/2π r ≈ 96/6.28 r ≈ 15.29
Answer: The radius of a circle with a circumference of 96 feet is approximately 15.29 feet.
