A circle is a plane geometric shape where the distance from the center to the corner of the circle remains the same. The radius is the distance from the center outwards. A circle has about 80% of the area of a similar width square. Below given an online geometry calculator to calculate the diameter of a circle based on the radius. Just input the radius value in the input field and the diameter of a circle from radius calculator will update you with the resultant value.

Calculate diameter of a circle from radius of about 15 cm.
D = 2 x 15
= 30 cm.
