Question

Check my work?

If a wheel with a radius of 30 inches spins at a rate of 500 revolutions per minute, find the approximate linear velocity in miles per hour.

89 MPH?

Answer 1

@thushananth01 If you're not too busy

Answer 2

V = r.w
w = 2.pi/T
w = 2.pi.f
v = r .2.pi.f
= 30000pi inches per min
89.24 mph

Yes you are right!

Answer 3

\[\frac{\ \pi*2\ *30\ *500\ *60}{12*5280}=\frac{625 \pi }{22}=89.2498 \text{ mph} \]
