1 Find the volume of the solid obtained by rotating the region
bounded by y=sin(5x^2), y=0, x=0, and x=√π/5 about the y-axis.
2 Find the volume of the solid obtained by rotating about the
y-axis the region in the first quadrant enclosed by x=5y and y^3=x
with y≥0
3 The base of a solid is the region in the xy-plane bounded by
the curves y=25−x2 and y=0. Cross-sections of the solid, taken
parallel to the y-axis, are triangles whose height...
