    ✅What is a Sphere?


    A sphere is a perfectly round ball, like a basketball or a marble. It looks the same from every angle!


    ✅Measuring it


    We only need one number:


    👉 Radius: The distance from the center to the surface.


    With this, we can figure out how big the ball is and how much space fits inside it!

    ✅The Formulas


    Volume = (4/3) × π × r³ (Space inside the ball)


    Surface Area = 4 × π × r² (Area of the outside skin)


    Where 'r' is radius.
