The radius of a circle is a line that starts at the center of the circle and ends somewhere along the perimeter of the circle. The diameter is a line that starts at the perimeter of a circle, goes through the center of the circle, and ends at the opposite perimeter of the circle. This a diameter is twice as long as a radius and can be thought or as consisting of two radii.

What is the diameter of a circle or a radius of in?
The diameter of a circle is twice its radius
When the diameter of a circle is 85.4 What is the radius of the circle?
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
What is the radius of a circle if the diameter is 14in?
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
