A circle with a radius of 3cm sits inside a circle with a radius of 11cm. What is the area of the shaded region? Round your answer to the nearest 100th. NOTE: The larger circle is shaded ( the smaller circle isnt )

Step-by-step explanation:

we know that

The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle

so

we have

----> radius of large circle

----> radius of smaller circle

assume

substitute

i think is g(1)=-1.

hope that i can

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
