The radius is half of the diameter so you divide the diameter in half. (divide by 2) If your trying to find the diameter if you have the radius you double it (multiply by 2)
Divide the diameter by 2.
Multipy by 2 for the diameter
To find the diameter of a circle you multiply the radius by 2 or d=r2
Diameter = radius * 2 Circumference = pi * diameter.
diameter = 2*radius

It easy...!! You just divide the diameter on 2...!! Because 2 radius are 1 diameter
Divide the diameter by 2. Diameter/2=Radius. Example: Diameter is 10cm then Radius is 10/2=5. - learnthetechnology.blogspot.com
Diameter = radius * 2 Circumference = pi * diameter.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Diameter = 2*Radius
Divide the Diameter by 2 to get the Radius
Divide the diameter by 2.
