find the angle in radians in the figure below if s=10 and r=7

Question

you haveto change it from radians to degrees 

Answer 1

I will assume that s is the arc length on a circle and r is the radius of the circle.  (Student:  Since no diagram is provided, you should clearly define these things in the problem statement.)  Then the angle in radians is

 

θ = s/r = 10/7 radians

 

To convert radians to degrees, multiply the radians by 180°/π.

 

θ = (180°/π)(10/7)
