wouldn't r be 16cm or.16m since 32cm is the diameter?

Thank you for noticing this mistake! I've updated the video to use half the diameter for r (which makes 0.16m).

would you please show where the rev went in the algebra? If I do dimensional analysis:

(.75 rev/sec)(2pir/1rev) the rev cancel out but I feel like I am missing a concept
