Rotating object angular velocity question

Homework Statement

A rotating object has angular velocity 10radians/s. After one min through what angle has the object rotated in 1) radians 2) degrees

Degrees = Radians x 180/Pi

I have tried and only come up with an answer of 3600 which i know is wrong

3600 what?

Any help is appreciated

Thanks in advance!

(rad/s)*(s)= radians

also, 1 min = 60 s.

So are we saying that 10*60 = 600 radians

Therefore 6.00 = d x Pi/180

6.00 = d x 0.0175

6.00/0.0175 = d

d = 343 degrees?

or is it... θ = (w0 + w)t/2

θ = (0+10) x 60/2

θ = 300 Degrees?

Thanks in advance

and π radians is 180°

so 600 radians is?

How can it be 600 radians that does not make sense! I am sorry but I don't understand

10 radians/s

in 1 s, object rotates 10 radians
in 60s...

so would the answer to the original question be

1) 600 Radians

2) 34377 Degrees

Thanks in advance
