4- If the drag force on a smooth sphere depends on the velocity (V), sphere diameter (D), viscosity (?), and density (?), use dimensional analysis to show the drag coefficient on the sphere is a function of the Reynolds number only. (15%) ?

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about the specified axis.

y = e^x, x = 0, y = 7π;    about the x-axis
