The shape of a gilli, in the gilli–danda game (see Fig.), is a combination of

two cylinders
a cone and a cylinder
two cones and a cylinder
two cylinders and a cone
Step 1: Look at the middle part of the gilli. It is like a straight pipe with the same circular cross-section everywhere. This is the shape of a cylinder.
Step 2: Now look at both ends of the gilli. Each end becomes narrower and comes to a pointy tip. This shape is like a cone.
Step 3: Since there are two ends, we have two cones.
Step 4: Together, the gilli is made of one cylinder in the centre and two cones (one at each end).
Final Answer: The shape is a combination of two cones and a cylinder.
