Answer:
Step-by-step explanation:
Picture this circumstance occurring within a circle. The center of the circle is where all the blades meet. That means that in terms of a circle's parts, these blades are the radii of the circle. And if they are all evenly spaced out, and there are 3 of them, the central angle in between each pair is 120 degrees (360/3). Once we know that, we can use the arc length formula for a circle which is
and filling in:
so
AL = 274.4 feet
Answer: I think you are talking about exponential so the question is more like (-4*3)^2 and they want you to expand it. So this ends up looking like (-4)^2 x (3)^2 so 16 X 9
