The radius (in cm
Given: edge of the cube = 4.2 cm
A right circular cone is a Cone whose height is perpendicular to the diameter (radius) of the base circle.
In a cube, a largest right circular Cone is formed when its base lies on one of the faces of the Cube and its tip lies on the opposite face.
∴ Diameter of largest right circular Cone in Cube = edge length of cube.
∴ Diameter = 4.2 cm
⇒ Radius = = = 2.1 cm
∴ Radius of the largest right circular Cone in Cube is 2.1 cm
