The diamiter of a circle is almost the same as the radius except the diameater is from side to side and radius is side to the middle.
A circle with a radius of 5.
The diameter of a circle is twice its radius.
The radius is 1.27cm
the answer is 20.54
Divide the diameter by 2. (The radius is 1/2 of the diameter.)
since the equation to get circumference is diamiter X pi, and the diamiter is 2x the radius, yes it would double the C of the circle ie before radius is 2, so diamiter is 4 4 X Pi 12.57... radius is 4 so the diamiter is 8 8 X pi = 25.13... that would double it.
Area of any circle = pi*radius squared
yes the radius is half the diameter. It goes from the edge of the circle to the centre.
radius=4cm diameter=8cm *radius is half the diameter
It depends on the ratio of what of the circle? Its circumference, diameter, area?
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
