Answer:
I think it is of the last option
Answer:
Volume = PI * radius^2 * height / 3
Volume = PI * 9^2 * 6 / 3
Volume = 3.14 * 162
Volume = 508.68

Step-by-step explanation:
Since the triangles are similar the ratios of the lengths of corresponding sides are equal.
tan Q = opp/adj = RS/QS = YZ/XZ = 9/12 = 3/4
I'm assuming there is a graph with both functions plotted. The solution would be the point at which these two functions intersect. That coordinates of x and y for that point will yield the solutions for x and y that solve the system of equations.
