Answer:
B
Step-by-step explanation:
area of the full piece of pie. π(8)²*60/360 (we know 60°, because it's an equilateral triangle)
32π/3
now subtract the area of the triangle
1/2(8)(4√3) = 16√3
32π/3 - 16√3
A proportional relationship runs through the origin and is a straight line. If you have a table, use the points to determine the slope. Is there one slope? If so, it is a proportion. If there isn't, it is not a proportional relationship (which is what you're looking for). Do you have a graphing calculator on hand? Those are extremely useful when you have an equation. Graph the equation and look at the image. Is it NOT straight? Does it NOT pass through the origin? This is how to find whether an equation is proportional or not.
