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
8 inches.
Divide the diameter by 2.
Well, if you know the diameter of the circle already, then you can divide it by half to get the radius. If you don't have the diameter however, then you simply have to find the middle of the circle and measure from the middle of the circle to the edge. That would be your radius.
If the diameter is 9 units then the radius (not raduis) is 4.5 units.
A circle with a diameter of 8 inches has a radius (not raduis) of 4 inches.
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
Assuming the diameter is 10.8 then the radius (not raduis) is 5.4 units.
Diameter is 8 and a half
The radius (not raduis) is 8 inches.
8 inches.
Divide the diameter by 2.
4 inches
A diameter of a circle (or sphere) is a straight line which is twice as long as its radius (not raduis).
The radius is half the diameter 15mm because the raduis is half the diameter so 30mm divided by 2mm it would be 15mm
radius is just 1/2 diameter so the answer is 34mm
135 feet!
