hello, I would like written solution for this question please. Sketch what the graph would look like.Let \( R \) be the region bounded by \( y=e^{x}, y=1\) and \( x=\ln 5\). For each part below, write down the integral (do not evaluate it) that represents the volume of the solid obtained by revolving \( R \) about (a) the \( x \)-axis and using the slicing (washer/disk) method. (b) the \( x \)-axis and using the cylindrical shells method. (c) the line \( x=-2\) and using the cylindrical shells method. (d) the line \( y=5\) and using the slicing (washer/disk) method.
