a radius is half the diameter of a circle
A diameter is a whole line and a radius is just half not a whole that is the difference
The radius of a circle is 1/2 of the diameter.
Radius is from the center of a circle to the outer edge. Diameter is from the outer edge to the opposite outer edge, i.e., through the center. The diameter has twice the length of the radius.
radius is half and diameter is the whole Expanding theabove statement: Diameter is the width of a circle; Radius is one half the width. In math, the radius refers to the distance from the centerpoint of a circle out to the edge.
Think of diameter like a dinosoaur. Dinosoaurs are big, and so is the diameter.
Outer radius minus inner radius Subtract the inside diameter from the outside diameter, then divide the difference by 2.
Radius = Diameter/2 Diameter = 2* Radius
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
radius = diameter/2
