. Do not submit the MATLAB output of these commands

1. Write a MATLAB command that calculates 29 25 x 65 + 73 + 4 2. Write a MATLAB command that assigns 5.6 and 7.8 to variables a and b, respectively, and then computes ea Va? + 2ab 2a 3. The surface area (SA) of a cylinder is given by SA2rh + 2r2 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 r and h, and then compute the surface area, SA. 4. Write a MATLAB command that creates a row vector V with the elements log10(111) sin where |cos(x)| is the absolute value of the cosine of x. Then, write the command to find the minimum of V. 00
