It is the length of the base of the semi-circle.
This is simply the pitch circle diameter multiplied by cosine of pressure angle, which is most commonly 20 degrees.
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
Diameter = circle's circumference/pi
The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius
