Multiply the radius of any circle by π, a numerical constant that begins with 3.142, and represents the relationship between a circle's diameter to its circumference. Multiply that product by 2. This will give you the circumference of the circle.

WebThe radius of curvature is computed by the equation: R = + t L TAN) ∆ N D 2 - (5) where: = total deflection angle of curve, degrees N = number of radius pipe L = standard pipe length being used, feet N = total deflection angle of each pipe From Figure 3, the radius of curvature can be expressed in terms of the drop and is given by the equation: Webradius minus the mid-ordinate, which forms the adjacent side. Remembering from your geometry that the adjacent and opposite sides of a right triangle squared and added to each other equal the hypotenuse squared. In the case of a one-degree curve with a radius of 5730', the midordinate works out to be - 1.006", close enough for railroad work. tooth aching after crown
