The circumference of a circle can be calculated as:

C = 2 π r

If we are given the value of C, we can find the radius by solving for r as follows:


r=(C)/(2\pi)

It's given that C = 106.76 cm. Substituting and using π = 3.14:


r=(106.76)/(2\cdot3.14)

Calculating:


\begin{gathered} r=\frac{106.76\operatorname{cm}}{6.28} \\ r=17\operatorname{cm} \end{gathered}

The radius is 17 cm
