The radius (in cm) of the largest right circular cone that can be cut out from a cube of edge 4.2 cm is

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
