The arc length is the product of the angle measure in radians and the radius.

... s = r·θ

So, the angle in radians is the ratio of arc length to radius.

... θ = s/r

To convert from radians to degrees, multiply by the conversion factor 180°/(π radians).

... y = s/r·(180°/π)

Then the angle is between

... 15/20·180/π ≈ 42.97

and

... 16/20·180/π ≈ 45.84

Suitable integers in this range are 43, 44, and 45.

One possible integer value of y is 44.
