Example of circumference in math
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. WebThe circumference of the given circle is shown in red. Solved Example onCircumference Ques: Find the circumference of the circle.
