Circumference of a circle:Formula= diameter * pi (approx 3.14)

Circumference = (diameter) multiplied by (pi)

Divide the circumference by 2*pi because 2*pi*radius = circumference

The circumference is about 56.548 cmUse this formula for future calculations: diameter x 3.1416 (Pi) = circumference

Circumference = 2 x {pi} x radius = {pi} x diameter

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

use the circumference formula of a circle circumference of a circle=2*pi*r pi=22/7 r-radius of a cirle Now the answer for the problem is 11.69

Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.

circumference = pi*diameter

The area is 346.639 cm2

12.732 (rounded)

The line from the centre of the circle to any point on its circumference

16 pi = almost exactly 50¼

Approximately 37.68 inches. The formula is the value of Pi times the diameter of the cirle. Pi rounds to 3.14. Thus 12 X 3.14 = 37.68.

The cicumference of any circle divided by its diameter is aways equal to pi.

circumference=r2pi

circumference of a cirle = 2*pi*r pi=3.14 r=radius
