Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
Circumference of a circle = diameter*pi Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
Circumference = diameter*pi
The diameter of the circle equals the circumference divided by Pi (3.14159....).
Circumference = (diameter) multiplied by (pi)
Circumference of a circle = (pi) x (diameter)
circumference of a circle = 2*pi*radius or pi*diameter
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
