What is the approximate area of the shaded sector in the circle shown below?

Alright, so first we find the area of the whole circle using pi r squared

12^2 pi = 144 pi

Now we use the proportions of the sector and the whole circle:

30:360 (degrees; we will be using the same for the other ratio)

= x:144pi

1:12 = x:144

This basically equals

12x = 144

x = 12, and now we multiply pi, so 12 x 3.14 = 37.7 cm^2.

The first option is correct.
