Read MoreProgram to calculate area and perimeter of equilateral triangle
Tringle is a closed figure with three sides. An equilateral triangle has all sides equal. Area and perimeter of an equilateral triangle can be found using the below formula, Area of equilateral triangle = (√3)/4*a2Perimeter of equilateral triangle = 3 * aLogic of CodeTo find the area of an equilateral triangle program uses square-root and power functions. The math library has both these functions and can be used to do the calculation in the program.The below code display program to calculate the area and perimeter of an equilateral triangle, Example Live Demo#include #include int main(){ int side = ...
Read MoreProgram to calculate area and volume of a Tetrahedron
A tetrahedron is a pyramid with triangular base i.e. it has a base that is a triangle and each side has a triangle. All the three triangles converge to a point. As in the figure, Code Logic − The code to find the area and volume of tetrahedron uses the math library to find the square and square-root of a number using sqrt and pow methods. For calculating the area we take a floating point and the value of the expression “((sqrt(3)*a*a))” is given to it. Another variable get the value of volume of the tetrahedron that is evaluated by ...
Read MoreProgram to calculate area of Enneagon
An enneagon also known as nonagon is a polygon with 9 sides. To calculate the area of enneagon the following formula is used, Area of ennagon = ((a2*9) / 4*tan (20°)) ∼= (6.18 * a2)Code Logic, The area of a polygon with nine sides is calculated by using the formula, ((a2*9) / 4*tan (20°)) ∼= (6.18 * a2). The value 6.18 is filled into a float variable called multiplier, this value then multiplied by the square of side of enneagon.Example Live Demo#include #include int main(){ int a = 6; float area; float multiplier = 6.18; ...
Read MoreProgram to calculate Area Of Octagon
An octagon is a polygon with eight sides. To calculate the area of octagon the following formula is used, Area of octagon = ((a2*2) / *tan (22.5°)) = ((2*a*a)(1+√2))Code Logic, The area of a polygon with eight side is calculated by using the above formula. The expression uses sqrt function to find the square root of 2. The value of expression is evaluated as a floating point value that is put into the float area variable.Example Live Demo#include #include int main(){ int a = 7; float area; float multiplier = 6.18; printf("Program to find area ...
