Double the Radius to Calculate the Diameter.
Using the Circumference And Area.
the diameter of a circle is two times the radius
well if the radius is given then the diameter is : d=2r. as for in a circle the diameter is : d=2(pi)r pi=3.14
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2rwhere d = diameter and r = radius
