Any wheel radius using d for diameter;
One revolution ----------------not supposed to look like exponent; it is a factor;
Or, .
For 3100 revolutions per minute, the linear speed in MILES per HOUR
-- best to simplify that --
and you can find the difference between diameter 13 inch and diameter 8 inches, the the speed.

w = angular velocity in rad/sec
r = radius of saw blade
To get you started...
3100 rpm = (3100 rotations/60 sec)* rad/rotation = 324.63 rad/sec
Next, for each blade: compute r, then compute v, then convert to MPH...
