Answer:
Pie= 3.14
Step-by-step explanation:
The enclosing boundary of a curved geometric figure, especially a circle.The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
pi is a number used to find the ratios between the circles circumference and diameter. This number is also used for many other formulas in Math and Physics.
pi ≈ 3.14
The formula for the circumference of a circle is C = 2πr
