Answer 1

A. 24pi mm^2
B. 72 pi mm^2
C. 144 pi mm^2
D. 216 pi mm^2

Answer 2

ok, so the circumference of the smaller circle is 12 pi, therefore its diameter is 12. this diameter is the RADIUS of the large circle. therefore, the area of the large circle is 12^2 pi or 144 pi. now, the area of the smaller circles is 6^2pi or 36 pi, but theres 2 of them so its 72 pi. 144pi-72 pi is 72 pi. the final answer is\[72 \pi \] MILIIMTERS SQUARED
