If the radius (not raduis) is 25 feet then the diameter is 50 feet.
Assuming daimeter = diameter and raduis = radius, 1 diameter = 2*radius.
Multiply by 2 ! A radius is half a diameter !
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
well if you have a radius then u just multiply the raduis by two and you get your diameter
