As the name suggests, equilateral triangle is the one that have equal sides and also it have equal interior angles of 60° each. It is also known as regular triangle because it’s a regular polygonProperties of equilateral triangle are3 sides of equal lengthInterior angles of same degree which is 60Circumcircle of a plygon is the circle that passes through all the vertices of a polygon. The radius of circle can be an edge or side of polygon inside the circle which is known as circumradius and center of circle is known as circumcenter. It can be inside or outside of ... Read More
What is Equilateral Triangle?As the name suggests, equilateral triangle is the one that have equal sides and also it have equal interior angles of 60° each. It is also known as regular triangle because it’s a regularpolygonProperties of equilateral triangle are −3 sides of equal lengthInterior angles of same degree which is 60Given below is the figure of equilateral triangleProblemGiven with the side of equilateral triangle the task is to find the area and perimeter of a triangle where area is the space occupied by the shape and perimeter is the space occupied by its boundaries.To calculate area and perimeter ...

What is rhombus?In geometry, rhombus is a quadrilateral with four sides of same length. Rhombus resembles with the shape diamond. If the diagonals of rhombus meet at right angle than it becomes square.Properties of rhombus are −equal sidesOpposite sides are parallel and opposite angles are equal making it parallelogramdiagonals bisects at right angleGiven below is the figure of rhombusProblemGiven with the diagonals, let’s say, d1 and d2 the task is to find the area and perimeter of a rhombus where area is the space occupied by the shape and perimeter is the space that its boundaries will coverTo calculate area ...

What is cuboid?Cuboid is a three-dimensional object with six faces of rectangle shape which means it has sides of different length and breadth. The difference between a cube and cuboid is that a cube has equal length, height and breadth whereas in cuboids these three are not sameProperties of cuboid are −six faces12 edges8 verticesGiven below is the figure of cubeProblemGiven with the length, width and volume, the task is to find the total surface area and volume of a cuboid where surface area is the space occupied by the faces and volume is the space that a shape can ...

Given with the number n the task is to calculate the factorial of a number. Factorial of a number is calculated by multiplying the number with its smallest or equal integer values.Factorial is calculated as −0! = 1 1! = 1 2! = 2X1 = 2 3! = 3X2X1 = 6 4! = 4X3X2X1= 24 5! = 5X4X3X2X1 = 120 . . . N! = n * (n-1) * (n-2) * . . . . . . . . . .*1ExampleInput 1 -: n=5 Output : 120 Input 2 -: n=6 Output : 720There are multiple methods that ... Read More
Given with certain values the program will develop an EMI calculator to generate the needed output. EMI stands for Equated Monthly Installment. So this calculator will generate monthly EMI amount for the user.ExampleInput-: principal = 2000 rate = 5 time = 4 Output-: Monthly EMI is= 46.058037The formula used in the below program is −EMI : (P*R*(1+R)T)/(((1+R)T)-1)where, P indicates loan amount or the Principal amount.R indicates interest rate per monthT indicates loan time period in yearApproach used below is as followsInput principal, rate of interest and time in float variableApply the formula to calculate the EMI amountPrint the ...
