Question

1-Find the volume of the solid formed by rotating the region enclosed by
y=e^1x+2, y=0, x=0, x=0.7
about the y-axis.

2-Use cylindrical shells to find the volume of the solid formed by rotating the area between the graph of x=y^9/2 andx=0,0≤y≤1 about the x-axis.
Volume = ∫10f(y)dy∫01f(y)dy where, find the f(y) and the voume.

3- x=y^5/2 andx=0,0≤y≤1 about the line y = 2 to find the volume and the f(y) by the cylindrical shells
