#### C Program to Find Area of a Circle

In geometry, the area contained by a circle of radius r is denoted by the symbol πr2. The Greek letter π represents the constant ratio of a circle’s circumference to its diameter, which is approximately equal to 3.14.

**Program:**

```
#include<stdio.h>
int main()
{
// declaring variables
float radius, area;
// inputs from user
printf("Enter Radius of Circle(in cm): ");
scanf("%f", &radius);
// calculating area
area = 3.14 * radius * radius;
// print result
printf("Area of Circle = %.2f cm\n", radius,area);
return 0;
}
```

**Output:**

Enter Radius of Circle(in cm): 10

Area of Circle = 314.00 cm
