How is the perimeter of a circle calculated?
Circumference means, ‘the perimeter of a circle’. The word has been derived from the Latin word circumferre means to carry around. The distance around a circular region is also known as its circumference. The ratio of circumference to diameter is approximately the same around 3.142. i.e.

How to find the perimeter of a flower bed?
So, the perimeter/circumference of the flower-bed is 56.5487 m. Example 2: Find the perimeter of the given circle whose diameter is 4.4 cm. Diameter of the circle (D) = 4.4 cm. We know the formula to find the perimeter of the circle if the diameter is given, namely π· D. Substitute the diameter 4.4 and Pi value as 3.14 in the above formula.
