Predict the outcome of the following mathematical calculations and verify that with MATLAB 58/2+4*3 57*9/2 4(2 3) 1/5 (6+3 8) (13/6) 1. Calculate the following values in MATLAB C = e4 + ln(4)-34+ln(2) B A.C.D Which one of the following is not a valid variable name in MATLAB? 2. Fred | Fred Fred ! Fred(1) Fred(2) #1Fred Fred! Hint: follow the rule in the handouts, or try in MATLAB; or use function isvarname 3. = 20. what is the size of Fred? How do Clear all the variables from workspace; type in Fred(5) you explain it? Clear all variables again and try: Fred nan(5,1); Fred(5) 20. What did change? Let's define "SA" as surface area of sphere calculated from 42 and "V" as sphere's volume calculated as Answer the following questions a. What is the surface area and volume of a sphere with radius 4? b. What is the surface area and volume of a sphere with diameter 4? c. What is the ratio of volume of a sphere with radius 10 to the volume of a sphere with radius 4. 5? d. Evaluate sphere volume for a vector of radii equal to [5 9 2 7] for 4 different spheres. 5. Repeat question 4 for a cube. Radius changes to edge width, but keep the variable name "r
