#### A cone is cut through a plane parallel to its base and then the cone that is formed on one side of that plane is removed. The new part that is left over on the otherside of the plane is called(A) a frustum of a cone                                   (B) cone(C) cylinder                                                     (D) sphere

Answer(A) a frustum of a cone

Solution

Cone – A cone is a three dimensional geometrical shape that tapers smoothly from a flat base to a point called the apex or vertex.

Frustum of a cone – It is portion of a solid that lies between one or two parallel planes cutting it

Cylinder – A cylinder is a three dimensional solid that has two parallel based joined by a curved surface at a fixed distance.

Sphere – The set of all points in three dimensional space lying the same distance from a given point.

Thus A cone which is cut through a plane parallel to its base and then the cone that is formed one side of that plane is removed then the new part which is formed is called frustum of a cone.
