# How to convert diameter to radius?

Just divide by two; half the diameter is the radius. For example, if you have a diameter of 6cm, just divide by 2. You will get half of the value, which is 3cm; this is the radius.

## Given this circumstance, how do you go from diameter to radius?

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.## In addition, you may be interested in is radius half of diameter?

The radius of a circle is the length of the line segment from the center of a circle to a point on the circumference of the circle and diameter is a line segment from one end of the circle to the other end of the circle passing through the center of the circle. So, the radius is half the length of the diameter.## In the same vein what is the formula of diameter and radius?

Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle. Using this definition, the formula for the diameter is: D = Radius × 2.## Do you have your own answer or clarification?
