The outer radius is 20/2 = 10 inches
A wheel with a diameter of 12 inches will have an angular speed of 560.2 revs per minute.

The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
roughly 62 (61.897846)
Find how far one revolution goes - this is the circumference of the wheel; from this the radius can be calculated: 1000 revolutions = 628m 1 revolution = 0.628m =62.8cm Circumference = 2{pi}radius (pi ~= 3.14) radius = circumference / 2{pi} ~= 62.8cm / (2 x 3.14) = 62.8cm / 6.28 = 10cm
1 revolution = 2PI radian. 2 revolutions = 4PI radian The angular speed of the Ferris wheel is 4PI radians . Multiply by the radius. The linear speed is 100PI feet per minute.
The relationship between revolutions per minute (RPM) and relative centrifugal force (xg) is: g = (1.118 × 10-5) R S2 where g is the relative centrifugal force, R is the radius of the rotor in centimeters, and S is the speed of the centrifuge in revolutions per minute. You can use this for any centrifuge, just measure the radius of the rotor from the center to outer edge.
If the wheel made 3000 revolutions and covered 45000 pi inches, then one revolution would cover 15 pi inches. That is the circumference. The circumference is equal to 2 times the radius times pi. Then the radius is 7.5 inches.
To convert revolutions per minute (RPM) to linear velocity in meters per second (m/s), you need the radius of the rotating object. The linear velocity can be calculated by multiplying 2π times the RPM by the radius in meters, and then dividing by 60. The formula is: linear velocity (m/s) = 2π * RPM * radius (m) / 60.
You can solve for revolutions per second using the equation (f = \frac{v^2}{r}), where (f) is centripetal force, (v) is linear velocity, and (r) is radius. Once you know linear velocity, you can calculate revolutions per second by dividing linear velocity by the circumference of the circular path.
Assuming rmp means revolutions per minutes, 2*r*pi*rpm (inches/minute).
In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.
Distance is number of revolutions times circumference. So divide the distance by the revolutions to get the circumference. Then divide the circumference by pi to get the diameter, and divide that by 2 to get the radius.
The outer radius is 20/2 = 10 inches
revolutions are angular velocity (w), so you need to know radius (r) to convert to velocity (v) meters per second. not linear velocity. v = wr. For example 30 revs per min is 30/60 revs per second; over a 2 meter radius velocity is 30/ 60 x 2 = 1 meter per second
