Answer:

How 3.14 is calculated?

The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus, pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14. Repeat this process with several different circles, and then average the results

What is the circumference of a 12 circle?

To find the circumference of a circle, you will use the formula C=2⋅π⋅r ; therefore the circumference C is 2⋅π⋅6≈38 inches.

How do you find the area and circumference of a circle?

Divide the area by pi; that gives you r ². Find the square root; that gives you r. Double it; that gives you the diameter. Multiply by pi; that gives you the circumference.

What is meant by circumference of a circle?

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.
