Answer:

The radius is 19.42 inches.

Explanation:

Start with the formula for finding the circumference of a circle, which is C=2
\pir.

Then, derive the formula in order to find the radius, which the formula should then look like r= C/2
\pi.

Finally, plug in the corresponding numbers, which is r= 122 inches/ 2
\pi. The final answer is 19.42 inches.
