Question

find the length of arc abc. use 3.14 for the value of π. round to the nearest hundredth of a cm.

Explanation:

Step1: Recall the formula for arc length

The formula for arc length \(L\) is \(L=\frac{\theta}{360}\times2\pi r\), where \(\theta\) is the central angle and \(r\) is the radius.

Step2: Identify the values of \(\theta\) and \(r\)

From the problem, \(\theta = 180^{\circ}\) and \(r = 38\) cm.

Step3: Substitute the values into the formula

Step4: Calculate the result

\(3.14\times38 = 119.32\)

Answer:

\(119.32\)
