To calculate the area of a circle in QBasic, you can use the formula Area = π * r², where r is the radius. First, prompt the user to enter the radius, then use the SQR function to compute the square of the radius. Finally, multiply the squared radius by the constant value of π (you can use 3.14159) and display the result. Here's a simple code snippet: INPUT "Enter the radius: ", r area = 3.14159 * (r ^ 2) PRINT "The area of the circle is "; area

Remember that the area of a rectangle is width * height: static int getArea(Rectangle r) { return r.width * r.height; }
Write a program that calculates the area of a triangle in QBASIC
Area of any circle = pi*radius squared
{Area s the area of cube} {Length is the length of one side of the cube} program AreaofCube; var Area,Length:real; begin write('Enter the length of cube: '); readln(Length); Area:=6*(Length*Length); writeln('The area of cube is ', Area, ' cm^2.'); end.

Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius, multiply it by π (approximately 3.14159), and you will have the area of the circle.
To calculate the area of a circle use this formula: pi x r2.
