Question

Consider circle Y with radius 3 m and central angle XYZ measuring 70°. What is the approximate length of minor arc XZ? Round to the nearest tenth of a meter. meters

Answer 1

Use formula for the length of the arc:

$\text{Arc Length} = (\theta\cdot \dfrac{\pi}{180^{\circ}}) \cdot r$, where $\theta$ is central angle.

Substitute $\theta$ and r=3 into formula:

$\text{Arc Length} = (\theta\cdot \dfrac{\pi}{180^{\circ}}) \cdot r=(70^{\circ}\cdot \dfrac{\pi}{180^{\circ}})\cdot 3=\dfrac{7}{6}\pi$.

Answer: $\text{Arc Length} =\dfrac{7}{6}\pi$.
