WebJul 17, 2024 · Throughout history, different civilizations have discovered that the circumference of a circle is slightly more than \(3\) times the length of its diameter. By the year 2000 BCE, the Babylonians were using the value \(3\dfrac{1}{8}=3.125\) and the Egyptians were using the value \(3\dfrac{13}{81}\approx3.1605\). [1] The value … WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. phoenix accounting thailand ltd
