I assume
has counterclockwise orientation when viewed from above.
By Stokes' theorem,

so we first compute the curl:


Then parameterize
by

where the
-component is obtained from

with
and
.
Take the normal vector to
to be

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



Answer:
C would be your answer as the formula for the volume of a cone is pi*r²*h/3
Step-by-step explanation:
B=x-5
To get x on its own you have to add 5 to both sides. This gives you:
b+5=x
or
x=b+5
Answer:
1.5 hamburgers per minute
Step-by-step explanation:
In 10 minutes, Justin can eat 15 burgers.
In 1 minute, Justin can eat 15/10 burgers.
15/10 = 1.5
10(1/2x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = - 52
x = -52/5
