Sphere Definition:
     A sphere is a solid figure bounded by a spherical surface.

Sphere Formula :
Volume of Sphere = (4/3)πr³
Curved Surface Area(CSA) of Sphere = 4πr²
where
        r = radius

Sphere Example :
Case 1: Find the volume and curved surface area of a Sphere with the given radius 3.

  Step 1: Find the volume.
            Volume = (4/3)πr³ = (4/3) * 3.14 * 3³ = 1.33 * 3.14 * 27 = 113.

  Step 2: Find the curved surface area(CSA).
            Curved Surface Area(CSA) = 4πr² = 4 * 3.14 * 3² = 12.56 * 9 = 113

The above example will clearly illustrates how to calculate the Volume, Curved Surface Area(CSA) of a Sphere manually.
