Please help me with a few questions- the situation is dire, so please help me answer this as soon as possible, and most accurately!!

Let R and S be the regions in the first quadrant shown in the figure. The region R is bounded by the x-axis and the graph of y = 4sinx. The region S is bounded by the y-axis and the graphs of y = 3 - 2x and y = 4sinx. 5 4 3 N S R X -1 - 2 2 -1 0 1 2 3 4 5 6 Part A: Find the area of S. Part B: Find the volume of the solid generated when R is revolved about the x-axis. Part C: Write, but do not evaluate, an integral expression that can be used to find the volume of the solid when S is revolved about the x-axis.For the regions A and B shown in the graph: Part A: Discuss the limits of integration. Part B: Set up an integral expression that represents the total area. Part C: Calculate the total area. The water level of a certain body of water is changing at a rate of W(1) = = sin 1- 2 Part A: Using correct units, explain the meaning of i2 W(t) dt in terms of the context of this problem. inches per hour, where t represents hours since 12 a.m. Part B: Write the integral that represents the number of inches that the water level changes from 10 a.m. to 3 p.m. Part C: Use your calculator to evaluate your integral from Part B. Explain the meaning of the answer in terms of the context. Part D: What is the average hourly number of inches that the water level changes for this lake in one day?
