Your answer would be (B. I don't know what the options are, but I did a quiz with this question, and picked B. And got a %100!
Circumference = 7.5
Area = 176.7
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

.
