Its diameter is: 21/pi = 6.685 inches rounded
66 feet
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
The circumference of a circle that has a diameter of 21 is about 65.97
If a circle has a diameter of 21 feet the circumference is: 65.97 feet (diameter x Pi = circumference).
The circumference of a 21 circle is: 65.97 (diameter x pi = circumference).
Circumference = 21*pi
Circumference = Diameter x pi = 21 pi = 65.973 inches(rounded)
The diameter is approximately 6.7
65.94
Its diameter is: 21/pi = 6.685 inches rounded
The circumference of a circle with a 21 mile diameter is 66 miles (approx).
It is: 21*pi feet
To find the diameter of a circle with a circumference of 66 inches, you can use the formula C = πd, where C is the circumference and d is the diameter. Rearranging the formula to solve for d, you get d = C / π. Plugging in the circumference of 66 inches, the diameter would be 66 / π ≈ 21 inches.
