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
