Diameter: 157/3.14 = 50 meters
Diameter = circumference/pi
Diameter = circle's circumference/pi
Divide the circumference by pi, and that will give you the diameter.
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
circumference = π x diameter π = 3.14159...
Diameter = circumference/pi
Diameter = circle's circumference/pi
The circumference of a circle can be calculated using the formula C = πd or C = 2πr, where d is the diameter and r is the radius of the circle. For a circle with a radius of 3 meters, the circumference would be C = 2π×3 =6π meters, or approximately 18.85 meters when rounded to two decimal places.
Divide the circumference by pi, and that will give you the diameter.
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
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).
