The circumference of the sphere is ~62.831 inches.
The diameter of this sphere is 20 mm
A sphere with a diameter of 20 units has a volume of 4,188.79 cubic units.
A sphere with a diameter of 20 cm has a volume of 4,188.79 cm3
Anywhere from a sphere 6 inches in diameter to a cylinder 80 feet tall and 20 feet in diameter, depending on design. They can be about any size desired.
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
20=2pir. 20/2pi is 3.1831in. So diameter is about 6.3662 inches (rounded)
If the area of a circle is 20 square inches the diameter is: 5.046 inches.
The circumference of a circle with a diameter of 20 inches is: 62.83 inches. (C = d x Pi)
The volume of a cylinder with a diameter of 10 inches and height of 20 inches is 1,570.8 cubic inches.
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 the diameter of a circle is 20 inches, the circumference is about 62.83 inches. (C = d x Pi).
