The area of a circle is the measure of the two-dimensional region enclosed by the circle. It is defined as the product of the radius of the circle squared and pi (approximately 3.14159). Here is a simple PL/SQL program that calculates the area of a circle given the radius:
PL/SQL Program Example to Find Area of Circle
This program calculates the area of a circle given the radius. It does this by declaring two variables: "radius" and "area". The "radius" variable is initialized to the value provided by the user, and the "area" variable is used to store the calculated area of the circle.
The program then uses a simple formula to calculate the area of the circle: area = pi * radius^2. The value of pi is approximated as 3.14159.
Finally, the program prints the calculated area of the circle to the output using the DBMS_OUTPUT package.
DECLARE
-- Declare variables
radius NUMBER := 3;
area NUMBER;
BEGIN
-- Calculate area of circle
area := 3.14159 * radius * radius;
-- Print the result
DBMS_OUTPUT.PUT_LINE('The area of the circle is: ' || area);
END;Output:
The area of the circle is: 28.27431
This program provides a basic example of how to use PL/SQL to perform calculations and print results. It can be easily modified to perform more complex calculations or handle different input values.
