The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
If the circumference of a circle is 62.8 inches the diameter is: 20 inches.
If the diameter of a circle is 20 inches, the circumference is about 62.83 inches. (C = d x Pi).
62.8 inches.
20/Pi = 6.37 inches
The circumference of a circle with a diameter of 20 inches is: 62.83 inches. (C = d x Pi)
r = 3.18 inches.
radius = 20/(2*pi) = 3.183098862 inches
The circumference of a circle = pi*diameter. 6 feet 3 inches = 6.25 feet, pi*6.25 = 19.63495408 feet or the circumference of the circle is nearly 20 feet.
The circumference of a circle is equal to 2 times pi times the radius of the circle. Therefore, if the radius of the circle is 10 inches, the circumference would be 2 times pi times 10 inches, or 20 pi inches. Pi is a mathematical constant with a value of approximately 3.14, so the circumference of the circle would be approximately 62.8 inches.
Circumference of the circle is: pi*20'
Circumference of a circle = 2*pi*radius or pi*diameter
