# Math Object

The JavaScript `Math` object allows us to perform mathematical tasks on numbers by providing some mathematical constant values and utility methods (for e.g trignometric and logarithmic functions).

Unlike other global objects such as `Date``Math` is not a constructor. All the properties and methods of `Math` are static and can be called by using `Math` as an object without creating an instance of it.

Note`Math` can only work with the `Number `type.

Some static properties of `Math`:

• `Math.E` : Euler's constant and the base of natural logarithms; approximately 2.718.
• `Math.LN2` : Natural logarithm of 2; approximately 0.693.
• `Math.LN10` : Natural logarithm of 10; approximately 2.303.
• `Math.LOG2E` : Base-2 logarithm of E; approximately 1.443.
• `Math.LOG10E` : Base-10 logarithm of E; approximately 0.434.
• `Math.PI` : Ratio of the a circle's circumference to its diameter; approximately 3.14159.
• `Math.SQRT2` : Square root of 2; approximately 1.414.

Some static methods of `Math`:

• `Math.abs(x)` : Returns the absolute value of x.
• `Math.cbrt(x)` : Returns the cube root of x.
• `Math.ceil(x)` : Returns the smallest integer greater than or equal to x.
• `Math.exp(x)` : Returns Ex, where x is the argument, and E is Euler's constant (2.718…, the base of the natural logarithm).
• `Math.floor(x)` : Returns the largest integer less than or equal to x.
• `Math.log(x)` : Returns the natural logarithm (loge; also, ㏑) of x.
• `Math.max([x[, y[, …]]])` : Returns the largest of zero or more numbers.
• `Math.min([x[, y[, …]]])` : Returns the smallest of zero or more numbers.
• `Math.pow(x, y)` : Returns base x to the exponent power y (i.e, xy).
• `Math.random()` : Returns a pseudo-random number between 0 and 1.
• `Math.round(x)` : Returns the value of the number x rounded to the nearest integer.
• `Math.sqrt(x)` : Returns the positive square root of x.
• `Math.trunc(x)` : Returns the integer portion of x, removing any fractional digits.

Try the following example in the editor below.

You are given a positive number A denoting the radius of a sphere as input. You have to calculate and print the volume of the sphere.

Volume of a sphere having radius R is given by (4 * π * R3) / 3.

NOTE: Since, the answer can be a real number, you have to print the ceil value of the volume. Ceil value of a real number x is the smallest integer that is greater than or equal to x.

Sample Input

`1`

Sample Output

`5`

Sample Explanation

`Volume of sphere having radius 1 units = 4.19Ceil value of volume = 5 `
