Circumference = (pi) x (diameter)
Diameter = Circumference/pi
62.8/pi = 19.98986 (rounded) which is awfully close to 20.
If the diameter of a circle is 20 inches, the circumference is about 62.83 inches. (C = d x Pi).
20 inches
62.8 inches.
The answer will depend on what is 20 inches: the radius or diameter or something else.
5*4 = 20 square inches
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
The circumference of the sphere is ~62.831 inches.
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).
If the circumference of a circle is 62.8 inches the diameter is: 20 inches.
20 inches
20/Pi = 6.37 inches
125.664 inches (rounded)
62.8 inches.
The answer will depend on what is 20 inches: the radius or diameter or something else.
r = 3.18 inches.
20=2pir. 20/2pi is 3.1831in. So diameter is about 6.3662 inches (rounded)
