My apologizes if I am posting it the wrong forum. I'm new to maple and I need help with the following question. I am able to produce the graph but I am not sure how to find the coordinates in order to do the follwoing steps. Any help with the following steps would also be appreciated.

The curves y=2*sin(x) and y=1 - (x/19) intersect at four points on the interval [0, 3π]. Let the points of intersection be P1(x1,y1)...p4(x4,y4), where x1<x2<x3<x4, and R is the region bounded by the two curves for x∈[x2,x3]
 
a. Plot the two curves and find the (x, y) coordinates of the four points of intersection (properly annotate your plot with a title, axes labels and a legend);
 
b. Find the area of R.
 
c. Find the perimeter of R.
 
d. Find the volume of the solid generated by revolving R around the line
