Diameter D Circumference C Area A While a circle symbolically represents many different things to many different groups of people including concepts such as eternity timelessness and totality a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point called the center.
How to find the circumference of a circle.
Determine the radius of a circle. Lets assume its equal to 14 cm. Substitute this value to the formula for circumference. C 2 π R 2 π 14 879646 cm.
You can also use it to find the area of a circle.
A π R² π 14² 615752 cm². Finally you can find the diameter - it is simply double the radius. D 2 R 2 14 28 cm. The radius the diameter and the circumference are the three defining aspects of every circle.
Given the radius or diameter and pi you can calculate the circumference.
The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. Circumference to Diameter Calculator. This circumference to diameter calculator is used to find the diameter of a circle given its circumference.
Just enter the value of the circumference.
Then tap or click the Calculate button. You can also select units of measure for both input data and results. Using the Diameter Calculator. You can enter the diameter and then compute radius and circumference in mils inches feet yards miles millimeters centimeters meters and kilometers.
Compute the area using these units.
Square mils square inches square feet square yards square miles acres hectares square millimeters square centimeters square meters and square kilometers. Diameter is the distance from one side of the circle to the other crossing through the center middle of the circle. The radius is half of the diameter. All of these values are linked with the mathematical constant π or pi which is the proportion of a circles circumference to its diameter and is nearly 314159.
The formula used to calculate circle circumference is.
C 2 π r. C Circle circumference. π Pi 314159 r Circle radius. Enter the radius of a circle.
The radius is the distance between the centre and any point on the outer edge of a circle.
Use the circle circumference formula to calculate the circumference of the following circles. 21 Circle with diameter 8cm. Solution Circumference π 8cm 251cm to 1 decimal place. 22 Circle with diameter 165cm.
Solution Circumference π 165cm 518cm to 1 decimal place.
23 Circle with diameter 10cm. For example the circumference of a circle with a radius of 4 inches is simply 2 x 314159 x 4 2513 inches. If the diameter is given instead first divide it by two then repeat the above process. For example if the diameter is 16 feet then the radius is 16 2 8 feet.
The circumference is therefore 2 x 314159 x 8 5026 feet.
