## Maths Formulas | Class 6 to Class 12

### Important Maths Formulas | Area Formulas

- Area of a Circle Formula = π r
^{2}

where

r – radius of a circle - Area of a Triangle Formula A=

where

b – base of a triangle.

h – height of a triangle.

- Area of Equilateral Triangle Formula =

where

s is the length of any side of the triangle.

- Area of Isosceles Triangle Formula =

where:

a be the measure of the equal sides of an isosceles triangle.

b be the base of the isosceles triangle.

h be the altitude of the isosceles triangle. - Area of a Square Formula =
*a*^{2}

- Area of a Rectangle Formula = L. B

where

*L*is the length.

B is the Breadth. - Area of a Pentagon Formula =

Where,

s is the side of the pentagon.

a is the apothem length.

- Area of a Hexagon Formula =

where

where “**x**” denotes the sides of the hexagon.

Area of a Hexagon Formula =

Where “**t**” is the length of each side of the hexagon and “**d**” is the height of the hexagon when it is made to lie on one of the bases of it. - Area of an Octagon Formula =

Consider a regular octagon with each side “*a”*units.

- Area of Regular Polygon Formula:

By definition, all sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:

where

*s*is the length of any side

*n*is the number of sides

*tan*is the tangent function calculated in**degrees**

- Area of a Parallelogram Formula = b . a

where

*b*is the length of any base

*a*is the corresponding altitudeArea of Parallelogram: The number of square units it takes to completely fill a parallelogram.

Formula: Base × Altitude - Area of a Rhombus Formula = b . a

where

*b*is the length of the base

*a*is the altitude (height).

- Area of a Trapezoid Formula = The number of square units it takes to completely fill a trapezoid.

Formula: Average width × Altitude

The area of a trapezoid is given by the formula

where

b1, b2 are the lengths of each base

h is the altitude (height)

- Area of a Sector Formula (or) Area of a Sector of a Circle Formula =

where:

C is the central angle in degrees

r is the radius of the circle of which the sector is part.

π is Pi, approximately 3.142

Sector Area – The number of square units it takes to exactly fill a sector of a circle. - Area of a Segment of a Circle Formula

Area of a Segment in Radians

Area of a Segment in Degrees - Area under the Curve Formula:

The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b, integrate y = f(x) between the limits of a and b. This area can be calculated using integration with given limits.

- Area of a Circle Formula = π r

### Root Maths Formulas

**Square Root :**

If x^{2} = y then we say that square root of y is x and we write √y = x

So, √4 = 2, √9 = 3, √36 = 6

**Cube Root:**

The cube root of a given number x is the number whose cube is x.

we can say the cube root of x by ^{3}√x

- √xy = √x * √y
- √x/y = √x / √y = √x / √y x √y / √y = √xy / y.

### Fractions Maths Formulas

What is **fraction** ?

Fraction is name of part of a whole.

Let the fraction number is 1 / 8.

**Numerator** : Number of parts that you of the top number(1)

**Denominator** : It is the number of equal part the whole is divided into the bottom number (8).
