Using the formula f=R/2, we can get the answer.
R=20 cm
Therefore f=20/2=10 cm
Since the focal length of a concave mirror is positive, let's leave it as it is.
Hope it helps u
here is ur answer...
R=(20cm)....
. focal length (f)=R½
f=(20×½)
f=(10cm...)✔✔✔
hence...
✨magnitude of focal length is 10 cm✨
hope it helps...☺☺
