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.

The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
If the radius of a circle is twice the diameter. The outer diameter of a circle the size of a circle. 32.25 mm = 1.27 inches
the combined diameter of all the outer planets is 363,546 kilometers, or 84% the diameter of the sun.
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.
Remembering that there is an inner core inside the outer core - the radius of the outer core/mantle boundary is about 3,400 km. (the diameter is twice the radius).
Consider going across the width of the pipe: Outer diameter = Thickness + Inner diameter + Thickness so 2*Thickness = Outer diameter - Inner diameter = 2.5 - 2.1 = 0.4 inches and therefore, Thickness = 0.2 inches.

The heater hose for a 2004 F-150 Heritage is 21 inches long. End number one has an inner diameter of 0.78 inches and an outer diameter of 1-inch. End number two has an inner diameter of 0.75 inches and an outer diameter of 0.78 inches.
For the inner area, multiply...the inner diameter x pi x the length of the pipe.For the outer area, multiply...the outer diameter x pi x the length of the pipe.
Outer radius minus inner radius Subtract the inside diameter from the outside diameter, then divide the difference by 2.
