Circumference
The circumference is a term used in geometry to describe the distance around a circle or any other closed curve
The circumference is a term used in geometry to describe the distance around a circle or any other closed curve. It represents the boundary or the outline of the shape. In simple words, it is the total length of the outer edge of the circle.
To calculate the circumference of a circle, we can use the formula:
C = 2πr
Where C represents the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. The radius is the distance from the center of the circle to any point on its edge.
So, when we multiply the radius by 2π, we obtain the circumference. This formula shows that the circumference is directly proportional to the radius; as the radius increases, so does the circumference.
It is important to note that the circumference is always measured in linear units, such as inches, centimeters, or meters, depending on the units used for the radius.
For example, let’s say we have a circle with a radius of 5 inches, to find its circumference, we can use the formula:
C = 2πr
C = 2π(5)
C ≈ 31.42 inches
Hence, the circumference of a circle with a radius of 5 inches is approximately 31.42 inches.
