A circle's diameter and radius are both intimately tied to its circumference, or the distance all the way around the outside of the circle. (Circumference is just a fancy word for the perimeter of any round object). So if you know the circumference, you can calculate the circle's radius...
A circle has an area of pir^2 and a perimeter of 2pir, where r is the radius. A useful measure of circularity compares these two in such a way that the value does not depend on how big the shape is or which units are used to measure it. Also, it will be easier to understand ...
Calculating the circumference using the radius. If we have the radius of a circle then to calculate the circumference we multiply pi (∏) by the radius (r) of a circle and then multiply by 2. For the circle above we have a radius (r) of 5cm, so lets calculate the circumference: And...
Calculate the area of a Circle in Excel The area of a circle is 3.14*(radius*radius). To create the formula in Excel, I could suggest the exponential function however, since the goal is just to find the square, we can twist the formula a little. The syntax to find the area of a c...
Java Program to calculate Circumference of a circle Now we need a value of radius which can be a user-provided value, alternatively, you can also pass in the program itself. Let see the first option if we go by user value our program will prompt the user to enter a value for the radi...
Therefore, the radius of the center circle is approximately 10 yards. Frequently Asked Questions What is pi? What is the difference between the diameter and circumference of a circle? What are the units used to express the circumference of a circle? How to calculate the circumference of a circ...
measurement. Perhaps measuring a straight line through the center of a circle would be difficult because of scale or accuracy, but the circumference could be a known value or easier to measure precisely. In these scenarios, we can use these equivalencies to then find diameter, radius, and area...

Now it's time to use the formula just discussed to calculate the area of a circle with a known radius. Imagine that you're asked to find the area of a circle with a radius of 2. The formula for the area of that circle isA= πr2. ...
The radius of a circle is the line segment from the center of a circle to a point on the boundary of a circle. Is a radius half of a diameter? Yes, the radius of a circle is half of the diameter because the diameter is the line segment that passes through the center of a circle...
