HEY MATE HERE IS YOUR ANSWER
A plane mirror can be considered as a spherical mirror of infinite radius of curvature. Focal length is half of radius of curvature and hence it is infinity. You can use the mirror formula also to get thefocal length of a plane mirror, where the image distance = − objectdistance.

hey,
Answer is simple.
INFINITY is the focal lenth. Focal length is the point half of radius. This radius is obtained by extenteding the edges of lens to obtain a imaginary circle. And then we get center of circle, C. Focal lenth is half of radius. So, technically a plane mirror never going to be a circle. But, in hypothetically we say it will be a circle of infinite radius. Hence, focal length is also INFINITE.
