The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
Diameter is twice the radius, so 18 feet.
Well, isn't that just a happy little question! If the diameter of the wheel is one yard, which is 36 inches, then the radius would be half of that. So, the radius of the wheel would be 18 inches. Just remember, there are no mistakes, just happy little accidents!
A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
