Answer:
Explanation:
To find the arc lenght, we use the formula
[tex]\begin{gathered} s=r\theta \\ \text{where}\colon \\ s=\text{arc lenght} \\ r=\text{radius} \\ \theta\text{ =angle} \end{gathered}[/tex]
Given:
Diameter = 24
Angle = 180°
To get the radius, divide the diameter by 2, so
[tex]\text{radius}=\frac{24}{2}\text{ = 12}[/tex]
To convert convert 180° into radians:
