The basic mathematics formula is generally used in basic maths and which are not only used in academic books but also in our daily lives. In the primary class, we all have learned about the general BODMAS rule. As one keeps on approaching the higher classes from six to ten one will come across the various mathematics formula based on various concepts such as algebra.
By practicing the questions and answers based on various formulas one can by heart each and every formula before appearing for the exams.
Some of the other concepts which have formulas are given below:
Formula for proportion
Trigonometric formulas and many more.
The basics of math display how a math problem can be solved with the help of some equations like the equation of forces, accelerations, or the work done. More importantly, they are used to provide mathematical solutions for real-world problems in our day-to-day life.
There are many types of equations, and they are found in many areas of maths. But the techniques used to examine them differ according to their type. It can be as simple as the basic addition formula or can be complicated as integration of differentiation.
The perimeter of Square = P = 4a
Where ‘a’ is the length of the sides of square
Perimeter of Rectangle = P = 2(l + b)
Where ‘l’ is Length and ‘b’ is Breadth
The area of Square = A = a2
Where ‘a’ is the length of the sides of a Square
The area of Rectangle = A = l × b
here ‘l’ is Length and ‘b’ is breadth
Area of Triangle = A = ½ × b × h
Where ‘b’ is the base of the triangle and ‘h’ is the height of the triangle
Area of Trapezoid = A = ½ × (b1 + b2) × h
Where b1 and b2 are the bases of the Trapezoid; h = height of the Trapezoid
Area of Circle = A = π × r2
Circumference of Circle = A = 2πr
Where ‘r’ is the radius of a Circle
Surface Area of Cube = S = 6a2
Where ‘a’ is the length of the sides of the Cube
The curved surface area of Cylinder = 2πrh
The total surface area of Cylinder = 2πr(r + h)
The volume of Cylinder = V = πr2h
Where ‘r’ is the radius of the base of Cylinder and ‘h’ is height of Cylinder
The curved surface area of a cone = πrl
Total surface area of cone = πr(r + l) = πr[r + √(h2 + r2)]
Volume of a Cone = V = ⅓ × πr2h
Here, ‘r’ is the radius of the base of Cone and h = Height of the Cone
Surface Area of a Sphere = S = 4πr2
Volume of a Sphere = V = 4/3 × πr
Where, r = Radius of the Sphere
Arithmetic mean (average) = Sum of values/Number of values.
Q1. What is a Formula?
Ans. A formula is a fact or the rule that is written with all the mathematical symbols. It usually connects two or more than two quantities with an equal sign. When one knows the value of one quantity the one can also find the value of the other using the formula respectively.
Q2. Give Examples of Some Basic Math Formulas.
Ans. Some examples of the basic math formulas:
Perimeter of a rectangle = 2 (length + width)
Area of rectangle = length × width
The perimeter of a square = 4 × side length
Area of square =Side length × side length
The volume of cuboid = length × width × height
Profit = Selling price - cost price
Loss = Cost price - selling price
Q3. What is the Importance of Learning Basic Math Formulas?
Ans. Following are the reasons for which we need to know and learn the basic maths formulas:
Basic Maths formulas help all the students to complete the syllabus in a unique do-learn-do pattern of study.
It improves the score in Board Exams and Entrance Examinations.
It makes complete Preparation easy on time.
