Okay Bright, so the central angle is 36 degrees, so according to the formula you have on the top of the screen, we have to do 36/360, which is 1/10 or 0/1. 

Then we multiply that by the radius squared. 12^2 = 144. 

Finally, we multiply 144 by 0.1, which is 14.4. So our answer is H. 14.4\pi.

Notice that we don't multiply the radius squared by \pi, since the answers are in terms of \pi.

Hope this helped!
