Question

Your code will calculate the diameter, area, and circumference of the circle with the

radius specified in the first text field. Note that: Diameter = 2*radius;
Area=m*radius2; Circumference=2* T*radius.
The diameter, area, and circumference are calculated in real time (e.g., when the
user enters 2 in the radius, the diameter automatically becomes 4; if the user
enters another 2 (the radius is 22 now), the diameter is automatically updated to 44)
The event occurs when the user releases a key Circle Calculator
Enter the radius:---------
Diameter of circle:----------
Area of circle:---------
Circumference of circle:------------

Answer 1

The formula for calculating the diameter, area, and circumference of a circle is explained, along with an example calculation.

Step-by-step explanation:

The formula for calculating the diameter, area, and circumference of a circle is:

Diameter = 2 * radius

Area = π * radius^2

Circumference = 2 * π * radius

For example, if the user enters a radius of 2, the diameter would automatically update to 4, the area would be approximately 12.57 square units, and the circumference would be approximately 12.57 units.
