HW8 #10

I seem to be stuck on this problem. I converted the rotational velocity so that the units would be rad/s instead of rev/min. I calculated the radius (in m) using the diameter (given in m). I plugged these values into the KE =(1/2)(m)(wr)^2 equation [w = lower case omega], but my answer was incorrect. What am I doing wrong?

Nevermind, I got it. I messed up in one of my conversions.
