##### Finding Area Of Circle In C Programming

Here’s a C program that accepts the radius of a circle and calculates and prints its area:

```				```
#include <stdio.h>

#define PI 3.14159

int main() {

printf("Enter the radius of the circle: ");

printf("The area of the circle with radius %.2f is %.2f.\n", radius, area);

return 0;
}

```
```
##### Output • In this program, we declare a `radius` variable of type `float` to store the input radius value, and an `area` variable of type `float` to store the calculated area.

• The user is prompted to enter the radius of the circle using the `printf` function, and the `scanf` function is used to read the input and store it in the `radius` variable.

• To calculate the area of the circle, we use the formula `area = PI * radius * radius`, where `PI` is a constant defined with the value of 3.14159.

• Finally, the program displays the calculated area of the circle using `printf` with the `%f` format specifier for floating-point values. The `.2` in `%.2f` specifies that the area should be displayed with two decimal places.
