Answer: 13 . 99 seconds
Step-by-step explanation:
The formula to find how long it will take an object to rotate through 6.9 revolutions at an angular velocity is given as :
t = 2π x number of revolutions / angular velocity
Therefore :
t = 2π x 6.9 / 3.1
t = 2 x 3.142 x 6.9 / 3.1
t = 43.3596/3.1
t = 13. 98696774194
to the nearest tenth
t = 13. 99s
 
        
             
        
        
        
I assume  has counterclockwise orientation when viewed from above.
 has counterclockwise orientation when viewed from above.
By Stokes' theorem,

so we first compute the curl:


Then parameterize  by
 by

where the  -component is obtained from
-component is obtained from

with  and
 and  .

Take the normal vector to  to be
 to be

Then the line integral is equal in value to the surface integral,
