Question

what is the arc length of arc cd in the circle below? circle a is shown with a radius labeled 10 feet and a central angle marked 40 degrees.

Answer 1

Hello,

2*π*10-->360°
2*π*10/360°-->1°
2*π*10/360*40-->40°


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

Answer 2

Arc length = 6.9708 feet.

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 (
`(central\ angle)/(360)`.

Arc length = 2 * 3.14 * 10 (
`(40)/(360)`.

Arc length = 62.8 (0.111).

Arc length = 6.9708 feet.

Therefore, Arc length = 6.9708 feet.
