In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure. Circumference may also refer to the circle itself, that is, the locus corres… WebCircumference = 2 * π* R = 2πR. 440 =2 * 3.14 * R. 440 = 6.28R. Divide both sides by 6.28 to get, R = 70.06. Therefore, the radius of the circle is 70.06 yards. But, since the diameter is twice the radius of a circle, the diameter is equal to 140.12 yards. Example 5. The diameter of the wheels of a bicycle is 100 cm.
