Question

The circumference of a circle is approximately 37.7 centimeters. Enter the radius of the circle in centimeters.

Answer 1

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!! :)
