This basic geometry video tutorial explains how to calculate the area and circumference of a circle given it's radius and diameter. Circle cross-sectional area to diameter and vice versa cross section conductor diameter intersection AWG calculation and conversion electric cable formula wire and wiring American Wire Gauge thick cross section area of a solid wire formula conductivity resistivity stranded wire litz length current - Eberhard Sengpiel sengpielaudio For example, if the diameter is 8 cm 8 ext 4 cm. Electrical - Electrical units, amps and electrical wiring, wire gauge and AWG, electrical formulas and motors Related Documents. Pi (pronounced like 'pie') is often written using the greek symbol ПЂ The formula for the area of a circle is ПЂ x radius 2, but the diameter of the circle is d = 2 x r 2, so another way to write it is ПЂ x (diameter / 2) 2.Visual on the figure below: ПЂ is, of course, the famous mathematical constant, equal to about 3.14159, which was originally defined as the ratio of a circle's circumference to its diameter. A circle of radius = 9 or diameter = 18 or circumference = 56.55 inches has an area of: 1.64193 Г— 10-7 square kilometers (kmВІ) 0.164193 square meters (mВІ) 1641.93 square centimeters (cmВІ) Area = ПЂ * (Diameter / 2) 2. Since the diameter is 22 cm, the radius is 11 cm, or half of that. If you're behind a web filter, please make sure that the domains *. and *. are unblocked. The area of a circle can be calculated using the diameter or the radius with two different formulas: A = ПЂr 2 or A = ПЂ(d/2) 2, where ПЂ is the mathematical constant approximately equal to 3.14, r is equal to the radius, and d is the diameter. The surface area formula for a rectangular box is 2 x (height x width + width x length + height x length), as seen in the figure below. Find the radius, circumference, and area of a circle if its diameter is equal to 10 feet in length. This tool will calculate the area of a circle from the diameter, and will convert different measurement units for diameter and area.

Thus, if there were a total of 28.26 squares, the area of this circle would be 28.26 cm 2 However, it is easier to use one of the following formulas: or where is the area, and is the radius. Radius is the same for all points on a circle's edge. Cable diameter to circle cross-sectional area and vice versa Round electric cable, conductor, wire, cord, string, wiring, and rope Cross section is just a two-dimensional view of a slice through an object. Example for volume of sphere Calculation. The circle is a simple closed curve ,where the distance between the center of the images and the circumference is called as radius. If the area of the circle is given, the formula d = sqrt (4a/pi) can also be used to solve for the diameter, where 'a' denotes the area. A = Circle area ПЂ = Pi = 3.14159вЂ¦ Diameter of a circle is given by. The constant pi, designated by the Greek letter ПЂ, is the ratio of the circumference to the diameter of a circle.
