Question

If the radius of the circle is 5 units, find the arc length of RQ

Answer 1

The radius of the circle is r = 5 units.

The formula for the arc length of RQ is,

`RQ=2\pi r*((\theta)/(360))`

Substitute the values in the formula to obatin the arc length RQ.

`\begin{gathered} RQ=2\pi\cdot5\cdot((142)/(360)) \\ =12.391 \\ \approx12.39 \end{gathered}`

So arc length of RQ is 12.39 units.
