The circumference of any circle is (pi) x (diameter),and of course, the diameter is double the radius.
The diameter of a circle is the length of a straight line drawn through the center of the circle to its edges.Or, measure the circumference of the circle and divide by pi (3.14159).Or you can multiply the radius times twoTo get diameter you have to find the radius and then double it to get the diameter
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
A circle's diameter is always double it's radius. So a circle of diameter 8.5 has a radius of 4.25. Half of 8.5
