What is the difference between the areas of a circular target region with radius 5 m and a target region with radius 7 m? round your answer to the nearest square meter. 36 m2 6 m2 75 m2 12 m2

Hence, the required area is:

                               75 m²

Step-by-step explanation:

The difference of the area of circular target  region with radius 5 m and a target region with radius 7 m is calculated as:

Area of circle of radius 7 m(A)- Area of a circle of radius 5 m(A')

Now, we know that the area of a circle of radius 7 m is given by:

Similarly the area of a circle of radius 5 m is given by:

Hence, the difference in the areas is given by:

which is approximately equal to:

                      75 m²

         Hence, the difference in the area is:

                              75 m²
