Define pi

• Pi is defined as a mathematical constant whose value is equal to the ratio circumference of any circle to its diameter.

• Pi is also equal to the ratio of a area of circle to the square of radius of circle(=A/r² ).

• Pi is just about equal to 3.141593 in the common decimal notation.

• Pi is involved in many formulae of mathematics.

• It is one of the most significant mathematical and physical constants.

• Pi is a dimensionless quantity i.e.) just a number without physical units.

• The symbol for pi is denoted as

Volume of a cube

Volume of a cube formula:

A cube is annihilation but the three-dimensional solid commodity accepting three ambit of the aforementioned length. Cube will accept six aboveboard faces. Cube is aswell accepted as approved hexahedron because it has eight according edges. The amount of vertices present in the cube is eight. In this commodity aggregate cube, we are traveling to altercate award the aggregate of cube.

Probability Calculator

conditional probability calculator:

A set of altitude C underlies the analogue of the anticipation of an event. If no restrictions added than the altitude C are imposed if artful the anticipation P ( A ), again this anticipation is alleged unconditional.

But, in abounding cases, one has to actuate the anticipation of an accident beneath the action that addition accident B whose anticipation is greater than 0 has already occurred.

" The anticipation of an even A , accustomed that an accident B has occurred, is alleged the codicillary anticipation of A accustomed B and denoted by the attribute P ( A / B )."

Accuracy

Definition of accuracy

While rounding decimals to degree of accuracy involves 2 rules to keep in mind:
Rule One: See what is our rounding digit is asked to do & see the right side of number of digits the rounding of decimals asked for. If that digit is less than 5, basically leave all digits to the right of it.
