a wheel is rotating at 8 radians/sec, and the wheel has a 47 inch diameter. to the nearest foot, what is the velocity of a point on the rim in ft/min?

Question

all i know is that you have to use the formula v=r.w

Answer 1

velocity=angularspeed*radius
radius=47/2 inches
angular speed is 8 rad/sec

Answer 2

r = 47/2 /12
v = omega in radians/min * r
v = 8 rad/sec *60 sec/min *(47/2)(1/12)

Answer 3

so i should do 8*47/2?

Answer 4

no
do
8*60 *47 /24

Answer 5

You have to do the units right !!!!!

Answer 6

ok i got it thnks
its 940 ft/min
