Looks like we're given
which in three dimensions could be expressed as
and this has curl
which confirms the two-dimensional curl is 0.
It also looks like the region 
is the disk 
. Green's theorem says the integral of 
along the boundary of is equal to the integral of the two-dimensional curl of over the interior of :
which we know to be 0, since the curl itself is 0. To verify this, we can parameterize the boundary of by
with 
. Then
Answer:
I'm sorry the pic isn't loading for meee but I wish u all the best
Answer:
25
Step-by-step explanation:
Subtract 15 from both sides then divide by 3.
Answer:
total area. 78m breadth.
Step-by-step explanation:
First, do 4 multiplied by 3 to find the area of one carpet. The answer is 12m. Then, do 12m multiplied by 23 to get the total area. The answer will be 276m squared. If you want to find width then do 3m multipled by 26 which is 78m.
