Question

5. A funnel is a combination of frustum of cone and
A) Hemisphere
B) Cylinder
C) Sphere
D) Cone
​

Answer 1

A funnel is a combination of frustum of cone and B) Cylinder.

Cylinder:

A cylinder is a three-dimensional solid figure that is defined by two parallel planes.

Explanation for incorrect answer:

A) Hemisphere:

The horizon, celestial equator, or ecliptic divides the celestial sphere into two halves, forming a hemisphere. It can't be a funnel with frustum and cone combined.

C) Sphere:

The celestial sphere is divided into two halves by the horizon, celestial equator, or ecliptic, forming a hemisphere. It cannot be a funnel combination of frustum of cone.

D) Cone:

A three-dimensional shape with a circular base is known as a cone. This means the base has a radius and a diameter. It cannot be a funnel combination of frustum of cone.

Hence, A funnel is made up of the frustum of a cone and a cylinder.
