Question

Find the length of an arc of an 8" radius circle if the arc measures 45°. 2 in. 8 in. 16 in.

Answer 1

Answer: 2π inches or 6.28 inches

Explanation:

To solve this problem you must apply the formula shown below:

`arclenght=(2r\pi)(C/360)`

Where r is the radius (r=8 inches) and C is the central angle (45°).

Then, you must subsitute values into the formula.

Therefore, you obtain that the length of the arc is:

`arclenght=(2(8in)\pi)((45/360)`

`arclenght=2\pi\ in=6.28in`
