Question

A circle with circumference 12 has an arc with a 330° central angle.

Answer 1

The answer is 11. I worked it out

Answer 2

arc length =11

Explanation:

To find the arc length , we take pi *2 r and multiply by the fraction of the circle

The circumference is 12 which is equal to 2 * pi *r

arc length = 12 * 330/360

arc length = 12 * 11/12

arc length =11
