Green's theorem says the circulation of 
along the rectangle's border 
is equal to the integral of the curl of over the rectangle's interior 
.
Given 
, its curl is the determinant
So we have
Theres only 4 but the answer is -15
40/x = 40/x+5 + 2/60
-> i don’t have a sketchbook or calculator at the moment so pls figure out the final answer yourself
Answer:
r = 8 ft
Step-by-step explanation:
The formula for circumference of a circle is
C = 2 * pi *r
We know the circumference is 16 pi
16 pi = 2 pi r
Divide each side by 2pi
16 pi /2 pi = 2 pi r / (2pi)
8 = r
