Explanation : Circle class is used to hold the value of the radius.It has one constructor. It takes the radius as an argument and assigns it to the local variable radius.; This class also has two methods getArea() and getPerimeter() to get the area and perimeter of a circle for the current radius.toFixed(2) is used to change the calculated value to two decimal places. The Math.PI Property. The Math.PI property represents the ratio of the circumference of a circle to its diameter. PI ( π) is a mathematical constant, which is approximately 3.14159: Math.PI = π ≈ 3.14159. Here is an example that calculates the area of. Java program to enter the radius of a circle and find its diameter, circumference, and area. There are you will learn how to find the diameter, circumference, and area of a circle in the Java language. Formula: D = 2 * r. C = 2 * PI * r. A = PI * r 2. where: r = radius of the circle. D = diameter of the circle. C = circumference of the circle. The mathematical formula for calculating the perimeter and area of the circle is given below: Area of circle = π * r * r. Perimeter of circle = 2 * π * r. Both formulae require the value of PI. So, in JavaScript, we have to use Math.PI property to get the value of PI. Let's see an example to calculate the perimeter and area of the circle. Example. Output: Enter the radius of circle 5. The area of C1 circle is: 78.55. Circumference of C1 Circle is: 31.419999999999998. Enter the radius of circle 6. The area of C1 circle is: 113.112. See also Python for Beginners Video Tutorial. Circumference of C1 Circle is: 37.704.
