Explanation:

Shadow is a dark area created when an object blocks the light source. The shape of the shadow depends on the shape of the object that is blocking the light. When an object is placed in front of a light source, it casts a shadow on the surface behind it. The shape of the shadow depends on the shape of the object.

Circular shadows are formed when the object blocking the light is circular in shape. So, any object that is circular in shape will form a circular shadow. However, there are some objects that will not form a circular shadow.

The following are the reasons why a shoe box will not form a circular shadow:

a) Shape of the object:
A shoebox is rectangular in shape. The shape of the object that is blocking the light determines the shape of the shadow. Since a shoe box is not circular in shape, it will not form a circular shadow.

b) Thickness of the object:
The thickness of the object also plays a role in determining the shape of the shadow. If the object is thick, it will cast a shadow that is darker and more defined. If the object is thin, it will cast a shadow that is lighter and less defined. A shoe box is thicker than a circular disk or a ball, and so it will cast a shadow that is darker and less defined than a circular shadow.

c) Orientation of the object:
The orientation of the object also affects the shape of the shadow. If the object is placed perpendicular to the light source, it will form a shadow that is more defined and darker. If the object is placed at an angle to the light source, the shadow will be less defined and lighter. A shoe box can be placed at different angles to the light source, and this will affect the shape of the shadow.

Conclusion:
In conclusion, a shoe box will not form a circular shadow because of its rectangular shape, thickness, and orientation. Only objects that are circular in shape will form a circular shadow.

A shoe box is the right answer because it is not spherical in shape whereas the ice cream cone base is spherical
