3. [Submit Answer on zyLabs] MATLAB has many built in functions and numbers. One of those is a built in representation of the number t, 3.14159... In MATLAB, you just need to write "pi to access that number. While that number is not 100% accurate (no representation of pi is), it has many more decimal places, and is much more accurate, than the approximation we sometimes use for rough calculations by hand, 3.14. 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 ii. Radius 10 meters and height 4 meters iii Radius 20km and height 8km
