Question

A circle arc has measure 22 cm and is intercepted

Answer 1

To solve this question, use the formula below:

`\text{arc length=}\theta\cdot r`

In this exercise,

arc length = 22 cm;

θ = 0.7 radians.

Substituting these values:

`22=0.7\cdot r`

Dividing both sides by 0.7:

`\begin{gathered} (22)/(0.7)=(0.7)/(0.7)r \\ 32.4=r \\ r=32.4 \end{gathered}`

Answer: The radius is 32.4 cm.
