Question

@mathmale can you help me with this A dog that has been tethered with a 20-foot lead makes the path shown here. If the length of the path is 45 feet, the measure of the angle  is _____ radians.

I can visualize what the path looks like, but gee, Big Boy, you seem to have a diagram there that you're not sharing with the rest of us!!!

The exact same principle applies here as in the previous problem:

s=arc length = r theta = (radius)(angle in radians).

Here you know the length of the path (which is an arc) and the radius; your task is to find the central angle (theta) in radians.  After that, you could, if you wanted to, convert that measurement of angle into degrees.
