Circle Calculator. This calculator will solve for the three unknown circle measurements from one known measurement (area, circumference, diameter, or radius). Plus, the calculator displays the steps, formulas, and sequence used to calculate each unknown measurement in the results.


Exercise 2: The circumference of a circle equals 10 meters.How long is the diameter of that circle? Solution: Solving this exercise requires to turn the equation around as the circumference is the known factor while the diameter is the unknown we need to find. As it has been said before the diameter is double the length the radius.


Calculating a circle's diameter is easy if you know any of the other dimensions of the circle: the radius, the circumference, or the area. It's also possible if you don't know any of the above dimensions but you do have a drawing of the circle. If you want to know how to calculate the diameter of a circle, just follow these steps.


How Do You Find the Circumference of a Circle if You Know the Diameter? ... Trying to find the circumference of a circle? Know the diameter? Then you can use the formula for the circumference of a circle to get the answer! Just plug the value for the diameter into the formula and solve. This tutorial shows you how!


To calculate the circumference of a circle, use the formula C = πd, where "C" is the circumference, "d" is the diameter, and π is 3.14. If you have the radius instead of the diameter, multiply it by 2 to get the diameter. You can also use the formula for circumference of a circle using radius, which is C = 2πr.


Solve area, diameter, and circumference, circle equations. Enter the circle area, diameter, or circumference and it will solve for the other two.


Finally, you can find the diameter - it is simply double the radius: D = 2*R = 2*14 = 28 cm. Use our circumference calculator to find the radius when you only have the circumference or area of a circle. If you wish to calculate the properties of a three-dimensional solid, such as a sphere, cylinder or cone, it's best to use our volume calculator.


The diameter of a circle is known as the straight line segment which passes through the center of the circle. This is also known as the longest chord of the circle. This online circumference to diameter converter helps you to find the diameter value from the given circumference at desired units.


2nd Way to Calculate Circumference of Circle: When You Know Radius of Circle. How to find the circumference of a circle: There is easy formula to finding out circumference of a circle using the diameter. Circumference of a circle (C) = 2πr, where π is pi and “r” is radius. Radius is half of diameter, so find out radius = r/2.


The distance from one side of the circle to the other, going through the center of the circle, is the diameter. The constant pi, designated by the Greek letter π, is the ratio of the circumference to the diameter of a circle. For any circle, if you divide the circumference by the diameter you get pi, an irregular number usually rounded to 3.14.
