length of arc cd=20*π/9=6,9813... (ft)

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.
