147 views

3.14 times the diameter of a circle is the formula used to calculate the circumference. To find the circumference, simply multiply the diameter by 3.14 (an approximation of π). For example, if the diameter is 5 units, the circumference would be 5 * 3.14 = 15.7 units. This formula is essential in geometry and helps in various practical applications involving circles.
