Diameter = circumference/pi
Diameter = circle's circumference/pi
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
circumference = π x diameter π = 3.14159...
You multiply the circle's diameter by 3.14 (Pi) to get the circumference.
Diameter = circumference/pi
Diameter = circle's circumference/pi
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
It is the ratio of the circumference (C) and the diameter (D) of a circle. Using pi and the diameter of a circle, you can work out the circumference.
circumference = π x diameter π = 3.14159...
You multiply the circle's diameter by 3.14 (Pi) to get the circumference.
Multiply the diameter by pi, and the answer will be the circumference.
Using pi as 3.14, the diameter of the circle is approximately 39.490446
The circumference of a 7-foot diameter circle using 3.14 for Pi is: 21.98 feet (diameter x Pi = circumference).
Pi x diameter
The circumference of a circle can be calculated using the formula C = π * d, where C is the circumference and d is the diameter. In this case, the diameter is 27, so the circumference would be approximately 84.78 units (assuming π is rounded to 3.14).
