Hi there!
The formula for the circumference of a circle is C = 2 x pi x r. Using this formula, we can plug in what we know and solve for the radius.
WORK:
37.7 = 2 x pi x r
18.85 = pi x r
r = 18.85/pi
or
r = 6
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
