A shuttle cock used for playing badminton has the shape of the combination of
(A) a cylinder and a sphere
(B) a cylinder and a hemisphere
(C) a sphere and a cone
(D) frustum of a cone and a hemisphere
Answer (D) frustum of a cone and a hemisphere
Solution.
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 thee dimensional space lying the same distance from a given point
Similarly hemisphere
Cone – A cone is a three dimensional geometrical shape that tappers smoothly from a flat base to a point called the apex or vertex.
Similarly frustum of cone
Hence we conclude that shuttle cock which is used for playing badminton has the shape of combination of frustum of a cone and hemisphere.
