Answer:
15.62
Step-by-step explanation:
(x + 4) / 3 = 12.....multiply both sides by 3, cancelling the 3 on the left side
x + 4 = 12 * 3
x + 4 = 36
x = 36 - 4
x = 32
The answer to that question will be A
Clearly, it cannot be A or D, since neither of those involve areas. They involved the length of something, whether the perimeter of the circle, or the length of the diameter. It can't be area of a circle either, because when you draw this out, it looks like a slice of cake. That means that the answer would be
C. Sector of a circle
