Well, isn't that just a happy little question! To find the radius of a circle, you simply divide the diameter by 2. Since the diameter of your circle is 6 meters, the radius would be half of that, which is 3 meters. Just imagine that radius as a little friend, bringing balance and harmony to your circle painting.
the radius is one half the diameter,or 6
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
