I need help with solving these word problems.

Marion rides her racing bicycle @ speed of 8 m/s. Bicycle wheels have a radius of 34 cm. What is the angular speed of wheels? How many times does each wheel go around during a 10-min race?

A car tire has radius of 33cm. Tire turns a total of 10,250 radians during trip to store. How many meters did car travel?

r = 0.34 m

omega r = 8 m/s

omega = 8/.34 radians/second

10 min = 600 s

600 * 8/.34 = total radians in 10 minutes

divide that by 2 pi radians per revolution

r = 0.33 m

angle in radians * r = distance travelled

10,250 *.33 = answer

tangenial speed=angularspeed*radius

tangential speed is given, as is radius.

for the second, revolutions/2PI=angularspeed*time

Is the answer for the 1st question ...23.5 rad/ sec?

Is the answer for the 2nd question...66 times?

Is the answer for the 3rd question...3382.5 meters?
