Answer:

13.448, rounded off: 13.5 ft

Step-by-step explanation:

r=\frac{C}{2\pi }

Where r = radius, C = circumference.

r=\frac{84.5}{2\pi } =13.448 = 13.5 ft

Answer:

r = 13.5 ft

Step-by-step explanation:

The circumference of a circle of radius r is C = 2(pi)r.

Here, C = 84.5 ft = 2(pi) r, or

          C = 84.5 ft = 6.28r

Dividing both sides by 6.28 results in the value of r:

r = 84.5 ft / 6.28 = 13.5 ft
