// 5 Questions for practice.. To improve in C.

// Q.1 Find a area of circle. Formula: A=πr2 (2 is square)

int main()
{
    float radius;
    printf("Calculate the area of a circle\n Enter a the radius: ");
    scanf("%f", &radius);

    float area_of_circle = 3.14 * radius * radius;
    printf("Area of the circle is: %f", area_of_circle);

    return 0;
}

// Q.2 Find the volume of cylinder. Formula: A=πr2h (2 is square)

int main()
{
    float radius;
    printf("Calculate the volume of cylinder\nEnter the radius: ");
    scanf("%f", &radius);

    float height;
    printf("Enter The Height: ");

    float volume_of_cylinder = 3.14 * radius * radius * height;
    printf("Volume of cylinder is: %f", volume_of_cylinder);

    return 0;
}

// Q.3 Perimter of a rectangle. Formula: perimeter= 2 x (width+height)

int main()
{

    float width, height;
    printf("Calculate perimeter of rectangle\nEnter the width of rectangle: ");
    scanf("%f", &width);
