How are diameter and circumference related
WebThe diameter is two times the radius, so the equation for the .circumference of a circle using the radius is two times pi times the radius. Solve the equation for the diameter of the circle, d= C/π. In this example, "d = 12 / 3.14." or "The diameter is equal to twelve divided by 3.14." Divide the circumference by pi to get the answer.

WebA = C [set area equal to circumference] πR2 = 2πR [use formulas for area and circumference of a circle] R2 = 2R [divide both sides by π] R2 – 2R = 0. R (R – 2) = 0. So the solutions are R = 2 and R = 0. The first solution, R = 2, gives us a circle with an area of 4π square units and a circumference of 4π linear units.

Using conversion factors, we obtain: ( 50 km 1 hr) ( 1000 m 1 km) ( 1 hr 60 min) ( 1 min 500 revolutions) = 5 m 3 revolutions = 1. 6 ¯ metres 1 revolution. So the circumference is: ( 1 revolution) ( 1. 6 ¯ metres 1 revolution) = 1. 6 ¯ metres. Share. Web1 de mai. de 2016 · I don't know why you flat earthers believe that the ratio of circumference to diameter is pi. That is only a limiting case for very small circles. I checked on my globe, and found that, for example, a circle of diameter 12,000 miles has a circumference of approximately 24,000 miles. That is a ratio of 2, not pi.
