a. Using MATLAB's pi approximation, then 3.14, write a script that calculates the volumes of cylinders ([area of circle] height) with i. Radius 5 meters and height 2 meters i. Radius 10 meters and height 4 meters. iii. Radius 20km and height 8km. b. Finally, use your script to calculate the differences between MATLAB's pi approximation and 3.14 for all of these calculations. Do you notice a trend
