10.5 in * 58 rev/min * 2 pi radians/rev = I get 3826 in/min
By the way, earlier I notice you were looking for a calculator:
yes,..the guy was teaching me how to do this problem
can you help..i need to use this link to figure out this problem..please guide me through:)
We are in quadrant 3
so add 180 degrees or pi radians to answer whatever we get first
click radians on upper right
type in the number 1
answer .785 ......
get 3.926...... radians
thank you very very much..i just have one LAST problem i need help with
A pulley of radius 11cm rotates 5 times in 64 seconds. Find the angular velocity of the pulley.
i think you have to use the formula
Yes, 5 pi/4
You could have seen that from the start because you probably know that the tan of 45 deg (Pi/4 radians) is 1 and pi/4 + pi = 5 pi/4
radius has noting to do with this
5 * 2 pi radians / 64 s
= (10/64) pi rad/s = .49 rad/s
.49 I mean
thank you soo much!!!!
