Question

The shortest distance from a line to the center of a circle of a radius 4 units is 12 units. The circle is reflected across the line. What is the radius of the resulting image?​

Answer 1

Answer: The radius will still be 4 units.

Explanation:

Since it is a rigid transformation, nothing of the shape will change excepts it location meaning that the radius of the shape will still stay the same.

The radius is 4 and after a reflection , the radius will still be 4.
