Question

Determine the angular displacement in radians for 4.3 revolutions

Answer 1

1 revolution = 2pi in radians

you have 4.3 revolutions. What do you do?

Answer 2

4.3 / 2?

Answer 3

4.3/2pi**** don't forget the pi. very crucial.

Answer 4

6.7?

Answer 5

how did you get 6.7

Answer 6

your equation should look as so:\[\frac{ 4.3 }{2\pi}\]

Answer 7

.7?

Answer 8

Yes. If you round it up. Good job.

Answer 9

Have u tried Kahn academy?

Answer 10

Just wondering.

Answer 11

no i haven't

Answer 12

Formula of Angular diaplacement is \[\theta=\frac{ s }{ r }\]
s is the distance covered by the object
R is radius
SO circle is 2phi
4.3\2 x 3.14 since phi=3.141
4.3\6.28
0.6847
0.7 approximately
this is the correct answer
