Oh, dude, it's like you're asking me to do math or something. Alright, so if the diameter is 20 inches, you just gotta multiply that by pi (which is around 3.14, in case you were wondering) to get the circumference. So, it's like 20 times 3.14... drumroll, please... 62.8 inches! Ta-da!
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
The radius will be half the diameter which is 20/2 = 10 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
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.
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
20 inches measured where on the wheel? Radius? Diameter? Circumference? Width?
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).
Circumference is diameter times Pi, you do the math.
The circumference of the sphere is ~62.831 inches.
20=2pir. 20/2pi is 3.1831in. So diameter is about 6.3662 inches (rounded)
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 radius will be half the diameter which is 20/2 = 10 inches
