Circumference = diameter*pi
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
Divide the circumference by pi (about 3.1416). The result is the circle's diameter.
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265
Circumference = diameter*pi
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
Diameter of a circle = circumference/pi
Divide the circumference by pi (about 3.1416). The result is the circle's diameter.
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
The diameter of the circle equals the circumference divided by Pi (3.14159....).
Circumference = (diameter) multiplied by (pi)
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
Circumference of a circle = (pi) x (diameter)
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265
circumference of a circle = 2*pi*radius or pi*diameter
