The linear speed of a body revolving at 1200 RPM in a circular path of 0.8 meter radius would be closed to?
Circumference of the path = pi times the diameter = 2 pi times the radius = 1.6 pi.1200 rpm = 1200 circumferences per minute = (1,200 x 1.6 pi) = 1,920 pi inches/min= 6,031.9 inches/minute (rounded)= 502.7 feet/minute (rounded)= 5.71 miles/hour (rounded)
How do you convert radian to revolution per minute?
"Radian" is a distance. "Revolution per minute" is a speed. Those two units measure different quantities, and they don't convert into each other. It'll help to know that 1 revolution is (2 pi) radians. So "one revolution per minute" is "2 pi radians per minute", etc.
How do you convert RPM to radians per second?
(x radians / second) x (1 revolution / 2 pi radians) x (60 seconds / minute)= (60x) / (2 pi) (revolution / minute)Multiply (radians per sec) by (60)/(2 pi) = 9.5493(rounded) to get RPM.
How do you convert revolution per min to rad per second?
('X' rev/minute) x (2 pi radian/rev) x (1 minute/60 sec) = 2 pi X/60 = 0.10472 Xrad/sec (rounded)
Find the speed of a vehicle whose wheels are 20 inches in diameter are making 53 rotations per minute.?
each rotation = circumference = (pi) x (diameter) = 20 pi inches(53 rotation/minute) x (20 (pi) inch/rotation) x (60 minute/hour) x ( 1 foot/12 inch) x (1 mile/5,280 feet) =(53 x 20 pi x 60)/(12 x 5,280) = 3.153miles/hour (rounded)

Surface speed of an eight inch diameter wheel at 2000 revolutions per minute?
The circumference of an 8-inch diameter wheel = d*pi = 8*pi. Each revolution will advance the wheel by one circumference, so 2000 revolutions per minute would be 2000 * 8 * pi = 1600pi feet per minute.
What day is international pi day?
March 14th on the 15th hour 9th minute and 2nd second. 3.141592 equals pi
How many radians does the minute hand of a clock rotate in 1.75 hours?
Since there are 2 Pi radians in one complete turn, then the minute hand turns 1.75 * 2 Pi radians in 1.75 hours.

Find the speed of a vehicle whose wheels are 20 inches in diameter are making 53 rotations per minute.?
each rotation = circumference = (pi) x (diameter) = 20 pi inches(53 rotation/minute) x (20 (pi) inch/rotation) x (60 minute/hour) x ( 1 foot/12 inch) x (1 mile/5,280 feet) =(53 x 20 pi x 60)/(12 x 5,280) = 3.153miles/hour (rounded)
What is the angular speed of the minute hand in radian per second?
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
How many times does a 32 inch pendulum swing in one minute?
Period ( left swing + right swing) of a simple pendulum = 2*pi * sqrt (L/g) in seconds. g = 32.2 feet per second2 L = 32 inches = 2.66667 feet Period = 2*pi * sqrt ( 2.66667ft/32.2) = 2*pi * 0.287777 = 1.808158 seconds for one period (two swings). Periods in one minute = 60 sec / 1.808158 sec = 33.183 periods in one minute. Times 2 = 66.366 swings in one minute.
When is the right time to eat pi?
The exact time to eat pi is March the 14 at 59 minute and 26 seconds after 1am (3/14 1:59:26)
A wheel is rotating at 250 revolutions per minute find the angular speed in radians per second?
1 revolution = (2 pi) radians1 minute = 60 seconds250 rpm = [ (250) x (2 pi) radians ] per [ 60 seconds ]= 26.18 radians per second (rounded)
