Hi there!

The formula for the circumference of a circle is C = 2 x pi x r. Using this formula, we can plug in the circumference and solve for r.

WORK:
28 pi = 2 x pi x r (initial equation)
28 = 2 x r (divide both sides by pi)
r = 14 in (divide both sides by 2)

ANSWER:
The first option, 14 inches.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
The radius would be 14 in.

28 pi / 2 = 14

Hope this Helps!!
