If I'm given a radius of 6 and an arc length of 15, what would my central angle, in radians, be?

Thanks!

The answer is 2.5 radians.

They gave you the formula in the question: arc length = radius × theta (the degree of the central angle), in radians

Just plug in the givens: 15 = 6x
Divide both sides by 6: x = 2.5
