Round your final answer to the nearest hundredth

The area of the shaded region is  

Step-by-step explanation:

The correct question is

A circle with radius of 4cm sits inside a circle with a radius of 11cm. What is the area of the shaded region?

The shaded region is the area outside the smaller circle and inside the larger circle

we know that

To find out the shaded region subtract the area of the smaller circle from the area of the larger circle

so

simplify

where

r_a is the radius of the larger circle

r_b is the radius of the smaller circle

we have

substitute

assume

substitute

what graph
