What is the area of the shaded region?

Round your final answer to the nearest hundredth.

Assuming the shaded region is the region in between both circles this is how you solve it:

Find the area of the 2cm circle then the area of the 4cm circle. Then subtract the area of the 2cm circle from the 4cm circle. To find the area of a circle use the equation A = πr^2. The area of the smaller circle given the values is 4π or 12.5663706144. The area of the bigger circle given the values is 50.2654824574. Then subtract and you get 37.6991118431. Which is approximately 37.70.
