Circumference Calculator - Find Circumference of a circle!

Circumference is basically the length when measured through the boundary of a circle. It is same as the perimeter of other polygons, just that it has a special name called 'circumference'. This is typically taught among basic maths calculations in schools. It is to be noted that some people falsely call circumference as circumfrence.

Circumference Of A Circle Calculator + Guide (And Formula ...

If you know the diameter (d), the circumference is C = πd. Then since we know that the radius (r) is half the diameter. Therefore the circumference in terms of the radius is C = 2πr. You can keep the circumference in terms of π or you can calculate using the π feature on your calculator or using 3.1415926 for π.

What is the area of a circle with circumference 1.8 m?

Diameter. The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2r. The Greek letter π. π represents the number Pi which is defined as the ratio of the circumference of a circle to its diameter or π = C / d. For ...
