Answer: r≈5.73 ft
Explanation:
The formula for circumference is C=2πr or C=πd. These 2 equations are equivalent to each other because 2r is d. This problem is asking for radius so we can ignore C=πd.
With 36 ft circumference, we can find the radius by plugging 36 into circumference.
36=2πr
r=36/(2π)
r≈5.73 ft
