Bao wants to visualize how the revenue for each type of media contributed to the total revenue for the four quarters.

Create a chart as follows to illustrate this information:

a$.$ Create a $3-$D Pie chart that shows how the revenue from each type of media $($range A$6$:A$11)$ contributed to the total revenue $($range F$6$:F$11).$

b$.$ Move and resize the chart so that the upper$-$left corner is in cell A$15$ and the lower$-$right corner is in cell E$30.$
