Question

a circle has a radius of 3. An arc in this circle has a central angle of 340°. what is the length of the arc ?

Answer 1

17.8

Explanation:

Find circle circumference:

C = 2
`\pi`r = 2
`\pi`(3) = 18.85

Find percentage of arc:

`(340)/(360)` = 0.94444444444.

Find arc:

0.94444444444 * 18.85 = 17.8027777777
