the formula is s = r*theta, where theta is given in RADIANS. so you should first convert that degree measure into radians then you can use the formula.

\(\large \theta = 36 \cancel {deg} \cdot \frac{\pi rad}{180 \cancel {deg}}=\frac{ \pi }{5} \text radians \)

so now, \(\large 12=\frac{\pi}{5}\cdot r \rightarrow r=\frac{60}{\pi}\)
