arcs and sectors key
Example 1: Calculating arc length Suppose a circle has a radius of 10 meters, and the central angle is 60 degrees. Convert degrees to radians: \( \theta = \frac{60}{180} \pi = \frac{\pi}{3} \) Arc length: \( L = r \times \theta = 10 \times \frac{\pi}{3} \approx 10.47 \text{ meters} \
