Assignment:
Q1.Find the volume of the solid generated by revolving the region about the y-axis. The region enclosed by the triangle with vertices (1,0), (1,2),(3,2)
Q2.Find the volume of the solid generated by revolving the region bounded by the given lines and curves about the x-axis.
y=2/x (this is 2 over x, couldn't make the fraction bar)
Find the volume of the described solid.
Q3. The base of a solid is the region between the curve y=6cos x and the x-axis from x=0 to x= pi/2. The cross sections perpendicular to the x-axis are isosceles right triangles with one leg on the base of the solid y=-x+3
