20=2pir. 20/2pi is 3.1831in. So diameter is about 6.3662 inches (rounded)
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
The circumference of a circle with a diameter of 20 inches is: 62.83 inches. (C = d x Pi)
If the diameter of a circle is 20 inches, the circumference is about 62.83 inches. (C = d x Pi).
The circumference of the sphere is ~62.831 inches.
20/Pi = 6.37 inches
The answer will depend on what is 20 inches: the radius or diameter or something else.
Circumference = (pi) x (diameter) Diameter = Circumference/pi 62.8/pi = 19.98986 (rounded) which is awfully close to 20.
The circle has a diameter of 6.366 inches.
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. For a circle with a diameter of 20 inches, the circumference is ( C = \pi \times 20 ), which is approximately 62.83 inches when using ( \pi \approx 3.14 ).
The diameter is the same as the length, so it is 20 inches. If you meant to say that the circumference was 20 inches, then divide by pi, which is 3.1416 20 / 3.1416 = 6.4 inches
If a circle has a diameter of 24 inches its circumference is: 75.4 inches (diameter x Pi = circumference).
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
