Question

Find the length of the arcin terms of pi.AB = [?]24 180°

Answer 1

Step-by-step explanation:

To find the arc lenght, we use the formula

`\begin{gathered} s=r\theta \\ \text{where}\colon \\ s=\text{arc lenght} \\ r=\text{radius} \\ \theta\text{ =angle} \end{gathered}`

Given:

Diameter = 24

Angle = 180°

To get the radius, divide the diameter by 2, so

`\text{radius}=(24)/(2)\text{ = 12}`

To convert convert 180° into radians:
