Circumference is the distance around the edge of a circle. To find the circumference the formula used is PI (usualy rounded to 3.14) X R sqaured. It is used in architecture, engineering, and in even more complex geometry.
Use: 2*pi*radius = circumference
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
Circumference is used in daily life by people who make cars, glasses, and contacts. Bakers use circumference when making pies.
We use it to calculate the circumference of a circle.
You use a protractor.
Circumference = 20*3.14 = 62.8 cm
Let's traverse the circumference of the park before we pace off it's diameter.
There is no need to square the answer. The circumference of any circle is 2 radius pi or 2rπ.
the circumference of the circle divided by pi (button or 3.14) - Maths
circumference of a circle = pi * diameter.
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
To find the diameter from the circumference, you can use the formula: diameter = circumference / π. For a circumference of 4.59 inches, the diameter would be approximately 4.59 / 3.14, which equals about 1.46 inches.
