Typical answer from The WikiAnswers Community: IT IS WRONG!The diameter is the distance across the circle, through its centre. It is double the radius, not the other way round!
A table which is 90 inch around its outside (circumference) is 28.648 inches (to 3 dp) across (diameter).
circumference = {pi} x diameter circumference = {pi} x 24ft ~= 75.4ft
You take the radius (or diameter). If radius you times it by two (since it is half of the Diameter) then times the answer by 3.14. If diameter, times the diameter by 3.14. then round the decimals.
If the circumference of the circle is 2.5 inches then its diameter is 2.5/pi = 0.796 of an inch rounded up to 3 decimal places
If the table is 60 inches across, the diameter is 60 inches.
Calipers can measure the diameter of round objects by using the outside jaws for external measurements and the inside jaws for internal measurements. By measuring the distance across the round object with the jaws, the caliper can provide an accurate reading of its size.

In the vaccum of space any object around 500 miles in diameter is forced to be round under its own gravity. Thats why all the planets are round.
24 foot round pool would be 24 feet across from the middle of the pool basically measure the diameter of the pool.
circumference = {pi} x diameter circumference = {pi} x 24ft ~= 75.4ft
The diameter of Jupiter is about 86,881 miles, while the diameter of the sun is about 864,340 miles. Therefore, the diameter of Jupiter could fit across the sun around 9.94 times.
The diameter of Earth is approximately 12,742 kilometers. This measurement represents the distance across the widest point of the Earth, passing through its center.
Two methods: 1. mark a point on the circumference of the round object; put a mark on the floor; line up the marks and roll the object along the floor until the mark retouches the floor; use the meter rule to find the distance between the marks on the floor. 2. measure the diameter of the round object using the meter rule and multiply it by π (pi ≈ 3.14159)
You take the radius (or diameter). If radius you times it by two (since it is half of the Diameter) then times the answer by 3.14. If diameter, times the diameter by 3.14. then round the decimals.
A custom made round table can be manufactured into any diameter (length across) that you would request. If you are looking for the standard of mass produced round dining tables, then they typically come in the following diameters: 36", 40", 42", 46" 48", 60", and 72". The website shop.com has a page of round tables in these diameters, and then some. Here is the direct link: http://www.shop.com/search/Diameter+of+round+Tables?
