Diameter is the straight line distance that crosses the circle by touching both the ends passing through the center. With the circumference (perimeter), diameter can be easily found along with the constant value pi. Perimeter is the distance around the circle. In this circumference to diameter formula, you can find the diameter of the circle just by dividing the perimeter with the pi value (3.14). You can manually calculate the value using this diameter from circumference formula.
