With one rotation, the wheel advances one entire circumference. The circumference is radius times (2 x pi). To convert from centimeters to meters, divide by 100. Finally, just divide the total number of meters by the circumference (in meters), to get the number of turns.

You can solve this as follows: 1) Multiply the 8 feet x pi, to get the circumference in feet. 2) Convert the feet to meters. Reminder: 1 foot is exactly 0.3048 meters.

Double the radius to 4.5 meters, which is the diameter. From there, multiply the diameter by Pi to get the circumference: 4.5m x Pi = circumference of about 28.27 meters

The circumference of a circle with a diameter of 2 meters is: about 6.283 meters. This is a fairly easy calculation - simply multiply the diameter by Pi (about 3.1416). The result is the circumference.

If the diameter (distance from one side of the circle to the other) is 26 meters then the circumference is 81.68141 meters. If the radius (distance from the center of the circle to the edge of the circle) is 26 meters then the circumference is 163.3628 meters. -D

What is the circumference of a circle with a diameter that is 8 meters? The circumference of a circle is C = diameter d times pi. pi = 3.14159 ... Circumference C = 25.133 meters.
