Introduction to sphere

Mr. Rishi teaches students the difference between a circle and a sphere using a deflated football. He explains that a circle is flat, while a sphere is round and solid. Priya, a student, is tasked with finding sphere-shaped objects at home. She identifies a laddu, a pea, and a bubble as spheres.
