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
.
Notice that we don't multiply the radius squared by, since the answers are in terms of .
Hope this helped!
