Question

Find the arc length of s is the figure. Round your answer to the nearest tenth.

Answer 1

Using the arc length formula, we have:

`\begin{gathered} s=2\pi\cdot r\cdot((\theta)/(360))\text{ (r: radius, }\theta=angle)\text{ } \\ s=2\pi\cdot5\cdot((115)/(360))\text{ cm (Replacing)} \\ s=2\pi\cdot5\cdot(0.319)\text{ cm (Multiplying)} \\ s=10.035\text{ (Dividing)} \\ \text{The answer is 10}.0\text{ (Rounding to the nearest tenth)} \end{gathered}`
