593

Step-by-step explanation:

3.14 × = 907.46

3.14 × = 314

907.46 - 314 = 593.46

 593.46 mm²

Step-by-step explanation:

The diameter of the big circle is 2(7) + 20 = 34

divide the diameter by 2 to get the radius (r) = 17

           Area = π·r²

                    = π(17)²

                    = 289 π

The diameter of the big circle is 20

divide the diameter by 2 to get the radius (r) = 10

           Area = π·r²

                    = π(10)²

                    = 100 π

The area of the shaded region is the difference between the area of the big circle and the area of the small circle.

                  = 289 π - 100 π

                  = 189 π

                  = 189(3.14)

                  = 593.46
