See below.

Explanation:

The circumference of a circle is the radius multiplied by two, then multiplied with Pi (3.14..) so if you have the circumference but not the radius, all you have to do is:

1: Divide the circumference by Pi.

(The product should be the diameter.)

2: Divide the diameter by two to get the radius.

Here's how to solve your particular problem:

  1. #188# #÷# #3.14# #=# #59.9#

  2. #59.9# #÷# #2# #=# #29.9#

#29.9# is the radius.

Hope it helped (:
