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
An 18-inch round object has a diameter of 18 inches, meaning it measures 18 inches across at its widest point. To calculate the circumference, you can use the formula (C = \pi \times d), resulting in approximately 56.5 inches. This size is commonly found in items like pizza, cake, or serving trays.
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 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.

To accurately measure a round table, use a measuring tape to find the diameter by measuring straight across the center of the table. Multiply the diameter by 3.14 (pi) to find the circumference.
A table which is 90 inch around its outside (circumference) is 28.648 inches (to 3 dp) across (diameter).
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
It has been going round the Sun ever since it was formed. We do not know exactly how many time that is but it is a large number.
Since earth is not round but elliptical in shape, it's diameter at equator is 12,756km and it's diameter at poles is 12,712km.
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)
To measure a round table accurately, use a measuring tape or ruler to find the diameter of the table. Measure across the widest part of the table, passing through the center. This measurement will give you the accurate size of the round table.
