To solve this question, use the formula below:
[tex]\text{arc length=}\theta\cdot r[/tex]
In this exercise,
arc length = 22 cm;
θ = 0.7 radians.
Substituting these values:
[tex]22=0.7\cdot r[/tex]
Dividing both sides by 0.7:
[tex]\begin{gathered} \frac{22}{0.7}=\frac{0.7}{0.7}r \\ 32.4=r \\ r=32.4 \end{gathered}[/tex]
Answer: The radius is 32.4 cm.
