Solution

A great circle is a circle drawn on the surface of a sphere with radius equal to the radius of the sphere.

Explanation:

A great circle is a circle drawn on the surface of a sphere, where the plane that cuts the sphere passes through its center, making the radius of the circle equal to the radius of the sphere. Great circles divide the sphere into two equal halves and represent the largest possible circles that can be drawn on the surface.
