This involves several factors, size of table, intended use, design, there are "GENERAL" formula's out there, for certain designs. It comes down to intended use and its stability. Example: In bowl turning, the general formula is 2/3 bowl area, 1/3 base area, this is for beauty an balance to the eye, that said, I have also seen bowls that shatter that formula and are still beautiful an pleasing. My suggestion is go to a furniture store and find a table that you like that is similar, then take some measurements. Good-Luck
The ratio of a round table to a pedestal base typically refers to their respective dimensions, particularly the diameter of the table to the height and width of the pedestal. While there isn't a standard ratio, a common guideline is that the diameter of the table should be about 2 to 2.5 times the diameter of the pedestal base to ensure stability and aesthetic balance. Ultimately, the specific ratio can vary based on design preferences and functional requirements.
According to eHow, your base area must support at least 1/3 of the table top area.
The ratio of the tabletop to the base typically refers to the proportions of their dimensions, such as length, width, or area. This ratio can be expressed as a fraction or a decimal, depending on the specific measurements taken. For example, if the tabletop measures 60 cm by 40 cm and the base measures 50 cm by 30 cm, the ratio of the tabletop area to the base area would be calculated by comparing these dimensions. To determine the exact ratio, you would need the specific measurements of both the tabletop and the base.
base - 2 squared
Mount Vesuvius has a base diameter of about 8 miles (13 kilometers) and its summit crater has a width of around 600 meters (1,969 feet).
20cm divided by 2N means it creates the pressure of 10Ncm2
To measure a table lamp's width, use a tape measure to determine the distance across the widest part of the lamp's base or shade, depending on which width you need. Ensure the lamp is on a flat surface for an accurate measurement. Record the measurement in inches or centimeters for your reference. If measuring for a specific space, consider the overall width to ensure it fits appropriately.
A round bath is a cylinder. The volume of a cylinder = area of the base x perpendicular height. Area of the base is πr2 (pi x radius x radius). The radius is half the diameter. The diameter is the width of the circular base. The perpendicular height will be the depth of the water, whether it's up to the top or up to where you have a bath.
The base of a cylinder is a circle. So we can use the area formula for a circle. Area = πr2 where r is the radius of the circle, and pi is the ratio of the circumference of the circle to its diameter.
The ratio of the height of an object to the length of its base.
the trick to finding the right size lampshade for your lamp is to measure the base of the lamp, times it by the height and the divide it by the width. this answer will be the diameter of your lampshade.
the volume is (base)(height)(width) ... base x height x width
