Question

If KJ=10, find the length of arc HJ

Answer 1

Explanation:

The arc length formula is

`L=(\theta)/(360)*2\pi r`

Theta is the angle that intersects arc HJ. That measure is 180-122 which is 58 degrees. We put that into the formula along with the radius measure of 10 to get:

`L=(58)/(360)*2\pi (10)` which gives us, rounded to the nearest hundredth,

L = 10.12 units
