Answer:
Arc length = 6.9708 feet.
Step-by-step explanation:
Given : circle a is shown with a radius labeled 10 feet and a central angle marked 40 degrees.
To find : what is the arc length of arc cd in the circle .
Solution : We have given that radius = 10 feet.
central angle = 40 degrees.
Arc length = 2 * pi * r ([tex]\frac{central\ angle}{360}[/tex].
Arc length = 2 * 3.14 * 10 ([tex]\frac{40}{360}[/tex].
Arc length = 62.8 (0.111).
Arc length = 6.9708 feet.
Therefore, Arc length = 6.9708 feet.
