To Find Diameter:
Multiply circumference by 0.3183, or
divide circumference by 3.1416
Other things to do with circles:
To find Circumference:
Multiply diameter by 3.1416, or
divide diameter by 0.3183
To Find Radius:
Divide diameter by 2, or
multiply circumference by 0.15915, or
divide circumference by 6.28318
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
The circumference of 1.5 diameter is: 4.712
Circumference = Pi * diameter
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
You divide the circumference by pi or 3.14.
Divide the circumference by Pi (3.1416)
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
diameter = circumference/pi
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
Circumference = pi*diameter So diameter = circumference/pi = 9.87 mi
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
