The radius of a circle is half the diameter.
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.

Half the diameter of a circle called the semicircle
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
The measure from the center of a circle to its edge is the radius.
The radius of a circle is half the diameter.

A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
Measure the distance from the centre of the circle to its circumference.
circle area is pi times radius squared

You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it.

circumference of a circle = 2*pi*radius or pi*diameter area of a circle = pi*radius squared
Circumference of a circle = 2*pi*radius
