A:

begin mathsize 12px style Hi space Nisha comma
Focal space length space and space radius space of space curvature space are space related space as
straight f equals straight R over 2 equals fraction numerator plus 24 over denominator 2 end fraction equals plus 12 space cm
Since comma space the space focal space length space of space mirror space is space positive space it space is space straight a space convex space mirror. end style
