A particle starts at the point (−3, 0), moves along the x-axis to (3, 0), and then along the semicircle y = 9 − x2 to the starti
ng point.
Use Green's Theorem to find the work done on this particle by the force field F(x, y) = 3x, x3 + 3xy2 .

Answer:
The circle has an area of about 1385 square mm.
Step-by-step explanation:
Let's recall that circles have an area that can be found with the following formula:
where r is the radius of the circle.
Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.
So, to the nearest whole number, the area of the circle is 1385 square mm.
