May 4, 2021 | education
| A circle is a series of equally distant points from the point that is the center of the circle.
In any circles, the ratio of the circumference of a circle to its diameter is always the same and is characterized by the number Π.
Formula for determining the circumference:
L = Π * D = 2Πr;
L is the circumference;
D is the diameter of the circle;
r is the radius of the circle;
Π = 3.14 …
Find the circumference:
L = 3.14 * 45 cm = 141.3 centimeters.
Answer: With a diameter of 45 cm, the circumference is approximately 141.3 centimeters.
