The best answer here is INFINITY, as all the formulas of geometrical optics will give you answers that make sense for plane mirrors by setting the radius to infinity.
The plane of a concave mirror refers to the flat surface that would be created if the mirror were extended outward from its curved surface. In optics, it serves as a reference plane for understanding the mirror's curvature and the behavior of light rays reflecting off its surface. The principal focus and the center of curvature are defined in relation to this plane, which helps in determining image formation and other optical properties.
Curvature is a general term to describe a graph. Like, concave or convex. Radius of curvature is more exact. If the curve in a 'small' section is allow to continue with the same curvature it would form a circle. that PRETEND circle would have an exact radius. That is the radius of curvature.
1/aAccording to Wikipedia,"The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point."
A plane mirror is a mirror which is completely flat, easier for your image to be reflected.

By increasing its radius of curvature to infinity.
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
Plane mirrors don't have one, I'd say it was 0.
In a concave mirror, the radius of curvature is twice the focal length.
The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
The relation between focal length (f), radius of curvature (R), and the focal point of a spherical mirror can be described by the mirror equation: 1/f = 1/R + 1/R'. The focal length is half the radius of curvature, so f = R/2.
There is a specific formula for finding the radius of a curvature, used often when one is measuring a mirror. The formula is: Radius of curvature = R =2*focal length.
A plane mirror is not curved so it does not have a center of curvature. Or if you want to be mathematically correct, you could say that it's center of curvature is at an infinite distance from the mirror.
The radius of curvature and the focal length mean the same so the radius of curvature is also 15 cm.
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
yes
The focal length of a mirror with a radius of curvature of 40.5 cm is half of the radius, so it is 20.25 cm. The mirror's face would be placed around this focal length distance from the person's face for optimal viewing.
