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
4*pi
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
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 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
4
Circumference is simply pi times the diameter. The approximate value of pi is 3.14, so for a circle 4 feet in diameter, the circumference is 4 x 3.14 = 12.56 feet, approximately.
A circumference of 12.57 inches.
