2) Write a script that will: (1) use an input statement to prompt the user to enter the radius of a circular disk; (2) then calculate the area of the disk based on the user input; and (3) use the fprintf function to print out the area using 6 decimal places. For example, your script shall work like this: Please enter the radius: 2.0 The area is 12.566371. 3) Write a script called Greeting that will first prompt the user for a name, and then prints a greeting with the name. Your script shall work exactly like the example below: >> Greeting What's your name? John Hello John! 4) In the metric system, fluid flow is measured in cubic meters per second (m/s). A cubic foot per second (ft/s) is equivalent to 0.028 m3/s. Write a script titled flowrate that will prompt the user for flow in cubic meters per second and will print the equivalent flow rate in cubic feet per second. Here is an example of running the script. Your script must produce output in exactly the same format as this: >> flowrate Enter the flow in m^3/s: 15.2 15.200 m^3/s is equivalent to 542.857 ft^3/s. 5) In hydrology, hyetographs are used to display rainfall intensity during a storm. The intensity could be the amount of rain per hour, recorded every hour for a 24-hour period. Write a matlab script that will first read in the data from 'raindata.dat' containing 24 hours' rain intensity in inches per hour; the script will then use a bar chart to display the intensities. Please show x- and y-axis labels and a title for the graph. 6) Write a script CalBMI to calculate a person's body-mass-index (BMI) using the equation: Weight (lbs) -X 703 Height (in)x Height(in) bmi =- Your script should work like the example below: >>CalBMI What's your weight in (lbs): 170 What's your height in [in]: 72 Your BMI is 23.1
