. Do not submit the MATLAB output of these commands

2. Write a MATLAB command that assigns 5.6 and 7.8 to variables a and b, respectively, and then computes ea Va+ 2ab - za 3. The surface area (SA) of a cylinder is given by SA = 2nrh+ 2ter2 where r is the radius and h is the height. Write the MATLAB commands to compute the surface area of a cylinder with radius = 4.5 and height = 6.7. You should first define the variables and h, and then compute the surface area, SA
