The SSC has notified SSC CGL new vacancy 2020 through its website. The candidates need to practice hard to score well in the exam.


Quantitative Abilities Topic 1 for SSC CGL 2020 Aspirant :


*Regular Polygons 

  • Regular polygons are the geometrical structures where all the sides and angles of the structure are equal. 
  • It includes triangle (Regular polygon with 3 sides), quadrilateral (Regular Polygon with 4 sides), Pentagons (Regular Polygon with 5 sides), etc. 
  • These are also called as an n-sided polygon, where n is the number of sides in a polygon. For example, a triangle is a 3- sided polygon with n=3.
  • There may be to types of regular polygons and these two are star and convex. 


Basic properties of Regular Polygons to learn before attempting SSC CGL EXAM:

  1. Symmetry: These types of regular polygons have a symmetrical reflection.
  2. The sum of each interior and exterior angle at a single vertex is always 1800.
  3. The exterior angle of regular polygon must be 3600/n, where n is the side of a regular polygon.
  4. Number of diagonals in a regular polygon can be calculated from the formula 12*n* (n-3) where n is the side of a regular polygon.

For example,

In a square where n=4,

The number of diagonals are = 12* 4* (4-3)

                                              = 12*4*1

                                              =2

                                                    

Quantitative Abilities Topic 1 for SSC CGL 2020 Aspirant :


*Right Prism

  • Right Prism is the solid geometrical structure bounded by polygon at its base and parallelograms at the other two sides and sides are perpendicular (900) to the ends.

  • It is a 3- dimensional structure.
  • On the basis of different polygons the name of right prism changes.

For example, when the base polygon is a triangle, it is called the right triangle

prism or when the base polygon is rectangular it is called right rectangular prism

and so on.


Formulas related to Right Prism are as follows:


  1. Volume of a Right Prism = Area of Base Polygon * Height of the right prism 
  2. Surface area of a Right Prism = (2 * Area of base Polygon) + surface area of parallelograms

  

Quantitative Abilities Topic 1 for SSC CGL 2020 Aspirant :


*Right Circular Cone

  • The right circular cone is a geometrical structure of a cone that has a circular section and its axis is perpendicular (900) to the base of the cone.
  • It is a cone with a circular base.

          Image result for image of right circular cone"

  • The right circular cone also has slant height as a measurement denoted by l which joins the vertex of the cone to the exterior point of the circular base of a right circular cone.
  • All measured elements in a right circular cone are equal.
  • A triangle formed from the vertex to the base of the right circular cone always forms an isosceles triangle. 

Formulas related to Right Circular Cone are as follows:

  1. Slant height l=h2+r2


  1. Lateral Surface Area of Right Circular Cone

    Lateral Surface Area = πrl


  1. Total Surface Area of a Right Circular Cone

Total Surface Area = π (r+ l) r


  1. Volume of Right Circular Cone:

Volume = 13πr2h



 All the best to All the aspirants of SSC-CGL2020 !
