I want know about circle circumfrance 22/7 value ho define with explaination please

Entire books have been written on this topic; it's far beyond the scope of a single post. I would recommend the book "The History of pi" by Petr Beckmann for a readable, non-technical introduction.

It is the ratio of the circumference to the diameter of any perfect circle.

The value is approximately 3.14159, but we can't represent it completely accurately since it is a non repeating decimal which seems to go on forever. It cannot be represented exactly by a fraction either, although the approximate value 22/7 is often used.

Pi also occurs in many other formulae in different fields of physics, making it one of the proper mysteries of nature.

Circumf = PI x Dia

Radius = 0.5 x Dia = Circumf / (2 x PI)

Radius = 0.5 x Dia = Circumf / (2 x PI)

If the circle is a drawing, you can measure the diameter and multiply by pi (3.14). The diameter is the widest crossing and goes through the circles center. If the circle is an object, you can wrap tape around it. Mark on the tape where it meets up with the start. Remove the tape, lay it flat and measure it.

Pi is a mathematical constant whose value is the ratio of any Euclidean plane circle's
circumference to its diameter; this is the same value as the ratio of a
circle's area to the square of its radius. It is approximately equal to
3.14159265 in the usual decimal notation.

You cannot have a semicircle that has a diameter of 2.500 mm and a radius of .425mm and a circumference of 3000mm

Circumference is equal to pi times the diameter. pi is = 3.14

The radius of a circle is always 1/2 the diameter

Area of a circle is pi time the radius squared

An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier

Initializing arrays. When declaring a regular array of local scope (within a function, for example), if we do not specify otherwise, its elements will not be initialized to any value by default, so their content will be undetermined until we store some value in them. The elements of global and static arrays, on the other hand, are automatically initialized with their default values, which for all fundamental types this means they are filled with zeros

include <iostream>

using namespace std;

int billy [] = {16, 2, 77, 40, 12071};

int n, result=0;

int main ()

{

for ( n=0 ; n<5 ; n++ )

{

result += billy[n];

}

cout << result;

return 0;

}

multidimensional array pseudo-multidimensional array #define WIDTH 5 #define HEIGHT 3 int jimmy [HEIGHT][WIDTH]; int n,m; int main () { for (n=0;n<HEIGHT;n++) for (m=0;m<WIDTH;m++) { jimmy[n][m]=(n+1)*(m+1); } return 0; } #define WIDTH 5 #define HEIGHT 3 int jimmy [HEIGHT * WIDTH]; int n,m; int main () { for (n=0;n<HEIGHT;n++) for (m=0;m<WIDTH;m++) { jimmy[n*WIDTH+m]=(n+1)*(m+1); } return 0; }

and now for trignometry

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int factorial(int);

int n = 3, i = 1;

double x, x2, b, PI, r;

char choice;

//r = x * (PI / 180)

cout<<"Please enter an angle value => ";

cin>>x;

cout<<"Is the angle value in Degree or Radian?"<<endl;

cout<<"Type D if its in degree "<<endl;

cout<<"Type R if its in radian "<<endl;

cin>>choice;

if((choice = 'R')||(choice = 'r'))

do{

i++; n = 3; x2 = 0; b = x2;

{

if(i == 1)

x2 = x - (pow(x,n) /factorial(n));

n = n + 2;

};

else

{

x2 = (x2 + ((pow(x,n)) /(factorial(n))) - (pow(x,n+2)) / (factorial(n+2)));

n = n + 4;

}

}while(abs(b - x2) > 0.000001);

else

//convert it to r

r = x * PI /180;

//cout<<"error occured/n";

cout<<"sin(x) = "<<x2<<endl;

return 0;
