Question 1171883: n a stretch of interstate, a vehicle's tires rotate at a rate of 840 revolutions per minute. The diameter of each tire is 26 inches. Find the following rounding to the nearest tenth if necessary.

12 inches = 1 foot
5280 feet = 1 mile
60 minutes = 1 hour
Convert the linear speed of the tires to miles per hour.?
Find the linear speed of the tires in inches per minute.?
Find the angular speed of the tires in radians per minute?

n a stretch of interstate, a vehicle's tires rotate at a rate of 840 revolutions per minute. The diameter of each tire is 26 inches. Find the following rounding to the nearest tenth if necessary.
12 inches = 1 foot

60 minutes = 1 hour
Convert the linear speed of the tires to miles per hour.?
%28pi%2A26%2A840%2A60%29%2F%285280%2A12%29 = 65 mph
Find the linear speed of the tires in inches per minute.?
pi%2A26%2A840 = 68,612.4 inches/min
Find the angular speed of the tires in radians per minute?
840%2A360%2A%28pi%2F180%29 = 5278 radians/min
