ANSWER

The relationship between the radius of curvature and focal length is that the radius of curvature is twice the focal length. In other words, focal length is half the radius of curvature.

In this case, focal length of the concave mirror is given as 10cm.

Hence, the radius of curvature of the mirror is 10×2=20cm.
