Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
12.5663706144, because the diameter (4) times Pi equals circumference
The circumference = Pai x Diameter = 3.14 x 4 = 12.56 cm
Circumference of circle: 4 times pi in inches
Multiply the radius by 2 to get the diameter. Then multiply the diameter by pi to get the circumference. Example: If radius = 2 inches, diameter = 4 inches circumference = 4 x pi = 4 (3.1416) or about 12.57 inches
The circumference of a cirlce that has a diameter of 3 inches would be about 9.42 inches
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
circumference = Pi * diameterdiameter = circumference / PiThe diameter is 4/Pi or approximately1.2732490258705930933383273555459.
The circumference of a cirlce can be found if you know either the diameter (the longest distance from on side on the circle to another) or th radius (half of the diameter). If you know the radius, multiply it by 2 to find the diameter. The cricumference = pi x D This means you times the diameter by pi (3.1415926535...)
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
To find the diameter divide the circumference of the circle by pi
12.5663706144, because the diameter (4) times Pi equals circumference
If a circle has a diameter of 4 bananas, it's circumference is 12.564 bananas
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
The circumference of the circle that has a diameter of 4 feet is: 12.57 feet
The circumference = Pai x Diameter = 3.14 x 4 = 12.56 cm
Circumference of circle: 4 times pi in inches
