== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.

If a circle measures 83 inches in circumference the diameter is: about 26.42 inches. You can easily do this calculation for other circles by dividing the circumference by Pi (about 3.1416).

30 pi = roughly 94.25 inches (rounded)

C=2(3.14)(5), which equals roughly 31.4. The circumference would be around 31.4 inches.

The diameter of a circle is found by dividing the circumference by pi (π). So, if the circumference of the circle is 4.5 inches, then the diameter would be 4.5 inches divided by pi (approximately 3.14), which is approximately 1.43 inches.

To get the circumference of a circle, the equation is pi * diameter. So, in this case, it is 2.5 * pi (3.14), or roughly 7.85. So, the circumference of the circle is about 7.85 inches.

Roughly 25.76 in. at its closest estimate.

Looks to be roughly 10 inches in length. Maybe between 6-7 inches in circumference.

The circumference is a length and cannot be measured in square inches. Either you meant circumference of 14.13 inches or area of 14.13 sq inches or something else. I cannot guess what and so the question is flawed to the extent that it has no meaningful answer.

Circumference = radius times pi you can find the radius by dividing the diameter in half and multiplying that by 3.14 In this case it'd be 2.5 x 3.14 = circumference

John Cena's biceps are thought to be about 23 inches in circumference. His chest has been measured at about 50 inches.

Assuming what you're asking is for the circumference (distance around the entire wheel) the formula is r*2*pi. In this case the circumference is roughly 157 inches.
