area of circle program in c | What are 2πr and πr2 in Circle 

We have a programming challenge to compose a program to find the area of circle program in c and Circumference of a Circle in C Language. What is the connection somewhere in the range of 2πr and πr2 in Circle? Prior to going to compose an answer in C. We need to know a few facts about the circle, Ie. area of circle in c, Radius of Circle, Diameter of Circle, and Circumference of Circle. 

We will discuss each point bit by bit with the assistance of pictures. What we are going to learn in this article, underneath is a rundown.

 What is Circle 

A circle is an adjusted closed shape, with no corner, and no edges. Where every one of the points in arrangement are at similar distance from its center. 

Span of Circle to find area of circle program in c 

Span is the distance from the center of the circle to any point on its circumference. 

Breadth of Circle to find area of circle program in c 

Breadth is nothing yet the greatest line in Circle. It's extremely simple to calculate the measurement of a circle, simply twofold the range of the circle. We can find a sweep of a circle by the given equation. 

Distance across of Circle Formula: Diameter = 2 * Radius. 

How Calculate Area of Circle to find area of circle program in c 

The area is a space covered by a circle, Circle area is reliant upon its range. We can calculate the area of the circle by given equation. 

The Formula for Area of Circle to find area of circle program in c 

Area of a Circle = πr2 or PI * Radius * Radius. 

Here PI esteem is fixed which is 22/7 or 3.1415926535, however for this issue, we are using a PI esteem up to 5 decimal digits, If you need to find out about PI click here. You can find the PI esteem up to 1,00,000 Decimal Digits. 

Area of Circle Circumference 

The circumference is a Latin word which means in English "Carrying Around" on in Hindi "परिधि". The circumference is a fixed or linear distance around it. At the end of the day, we can say that the length of the circle in case it were opened up and fixed to a line section. 

Recipe for Circumference of Circle to find area of circle program in c 

Circumference of Circle = 2πr or 2 * PI * Radius 

Clarification of area of circle program in c 

Presently we have both formulas(Area and Circumference), We simply need to place the R or Radius value in the both offered Formula to find area of circle program in c 

Model 1: Radius of a Circle 

Assume the worth of the Radius is 10.5, presently put a similar worth in the equation. We definitely realize the PI esteem which is 3.14159 

Area of Circle = πr2 or PI * Radius * Radius. 

area of circle in c = 3.14159 * 10.5 *10.5 = 346.360291 

Circumference of Circle = 2πr or 2 * PI * Radius 

Circumference of Circle = 2 * 3.14159 * 10.5 = 65.973389 

So here is a Final answer is = 346.360291 and Circumference is = 65.973389.
