Question

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 1

Hint: In the above question, we will first draw the diagram of a shuttlecock, then, we will find the shape of the combination.

Complete step by step answer:
We have been asked to find the shape of the combination of a shuttlecock used for playing badminton.
We will draw the diagram of shuttlecock as shown below,

Now, if we consider the part (I) of the shuttlecock, we can clearly say that, it is in a shape of hemisphere as shown below,

Again, if we consider the part (II) of the shuttlecock, we can clearly say that, it is in a shape of frustum of a cone as shown below,

Therefore, the correct option is D.
Note: In the question, you must have to draw the diagram of the shuttlecock, otherwise, it is very difficult to visualize the combination of shape a shuttlecock is made up of. Most of the time, students choose option C, i.e. a sphere and a cone. But only if we draw the diagram, we will realize that it is a frustum and not a cone, also that it is a hemisphere and not a sphere.
