circumference of a circle = diameter*pi or 2*pi*radius

I believe no, 3.14 is the circumference of a circle that has a diameter of 1 inch.

The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .

The circumference of a circle with a diameter of 1 is Pi: 3.1416

The circumference of a circle if the diameter is 1 equals 3.1412 (π).

If a circle has a circumference of 3.14 (pi) the diameter is: 1

The circumference of a circle if the diameter is 1 cm will be Pi (about 3.1416).

About 3.14 inches (3.14159 to greater precision - it is the diameter x pi)

circumference = 2 * pi * r ----> pi is a constant in this case circumference = 2 * 3.142 * 10 ------> radius is 1/2 of a diameter So, circumference of this circle is 62.84 inches

The circumference is Pi

You need the formula circumference = pi x diameter pi = 3.14.. This is by the way the definition of the special number pi.

I would think it would double also. Say Circle A has a diameter of 1 inch and Circle B has a diameter of 2 inches. To get the circumference, you multiply the diameter by pi (3.14). So 1 x 3.14 = 3.14 so that is the circumference of Circle A. To get the circumference of Circle B you need to multiply 2 x 3.14 = 6.28. And 6.28 is twice 3.14 so I would think the circumference doubles.
