C = pi d
By algebraic rearrangement
d = C / pi
the Circumference is pi times 2 times radius
If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= 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
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
PI times the DIAMETER
Circumference of a circle = (pi) x (diameter)
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The formula for the circumference of a circle is pi * diameter or (2 radius.)
The formula for finding the circumference of a circle is:-circumference of a circle = pi * the diameter of circlewhere The value of pi is approximately 3.14thus the circumference = 3.14*1.5 = 4.71 meters
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
circumference of a circle = 2*pi*radius or pi*diameter
Formula: diameter = pi / circumference
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 or the length (distance around the circle) is pi x D where pi is 3.14159........ and D is the diameter of the circle
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
