Sphere FormulaSphere is a solid 3 dimensional (xaxis, yaxis, and zaxis), geometrical shape, symmetrical circularshaped object. It does not have any flat surfaces, edges, and vertices. Sphere examples are football, Basket Ball, World Globe, Plants, and more. Characteristics of a Sphere A list of Characteristics of a Sphere is given below 
Component of Sphere A Sphere contains the following components  Diameter  The longest line that passes through the center of a Sphere is called Diameter. It is denoted by D or d. Radius  Half of a Diameter is called radius. It is denoted by R or r. Formulas of a SphereThe below table shows the three main formulas of a Sphere 
Where, r=radius of a Sphere π =22⁄7 or 3.14 D = Diameter of a Sphere A = Area of a Sphere V = Volume of a Sphere Example 1:If the radius of a sphere is 5 cm, then calculate the following:
Solution: Given  Radius of a Sphere (r) = 5 cm (i) Diameter of a Sphere (D) = 2r = 2×5 = 10 cm(ii) Surface area of Sphere (A) = 4πr^{2} = 4×3.14×5×5 = 314 cm^{2}(iii) Volume of a Sphere (V) = (4⁄3)πr^{3} Example 2: Write a C program to calculate the following 
Code: Output: Enter radius of a Sphere 5 Diameter of a Sphere is = 10 Area of a Sphere is = 314.000000 Volume of a Sphere is = 523.333351 Example 2: Write C++ program to calculate Sphere Formulas  Code: Output: Enter Radius of Sphere : 9 Diameter of Sphere = 18 Area of Sphere = 1017 Volume of Sphere = 3052 Example 3: Write a Java Program to calculate diameter, area, and volume of a Sphere. Code: Output: Diameter of a Sphere = 14 Area of a Sphere = 616.000000 Volume of a Sphere = 1437.33333333464 Example 4: Write a PHP program to calculate following Sphere formulas 
Code: Output: Diameter of the Sphere = 36 Area of the Sphere = 4073.1428571466 Volume of the Sphere = 24438.857142879
