The Absolute Best Books to Ace Pre-Algebra to Algebra II Arc Length and Sector Area – Example 1: Find the length of the arc. Round your answers to the nearest tenth. \((π=3.14), r=24\) \(cm\), \(\theta=60^\circ\) Solution: Use this formula: length of a sector \(=\color{blue}{(\frac{θ}{180})πr}\) length of a sector \(=(\frac{θ}{180})πr\) \(=(\frac{60}{180})π(24)=(\frac{1}{3})π(24)=8×3.14 \cong 25.1 \) \(cm\) Arc […]
