Explanation:
The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature. It is important to note up front that this is an approximately true relationship.

Answer:
relation between focal lenght and radius of curvature
C=2f
C=40
40=2f
f = 40/2
f= 20cm
hope it help
