Convert rev/min to radians per min:
(7 rev/14 min) * (2pi rad/1 rev) = pi radian/min
Convert rad/min to rad/sec. This is the angular velocity:
(pi rad/min)*(1min/60 sec) = pi/60 rad/sec
Linear velocity = angular velocity * radius
(pi/60 rad/sec) * 30ft = 0.5pi ft/sec
Convert ft/sec to in/sec:
(0.5pi ft/sec) * 12 in/1 ft = 6pi in/sec

Well, the interest literally mean the amount that add up to your previous capital that you invest in the past.
If you invest an amount of money and get an interest revenue out of it, the amount of your capital will be increased , not decreased
The answer is B. Mark as brainliest if this helped you out :). (It would be 66 inches long)
