Best Answer

the diameter of a circle is from one side of the circle to the other, and the raduis is always half, because the raduis is from the side to the middle, so the answer is 18

Radius is half the diameter. 36/2=18

It is 18 centimeters because your radius is exactly half of the diameter in any circle

36 feet.

72, double the radius because radius is half of the whole diameter.
