In this problem the roofing company is estimating total cost of the roofing project.

Given:

Label	Dimension 1	Dimension 2
Gymnasium Roof	400	200
Auditorium Roof	300	300

Instructions:

• Construct objects using the three attributes for each roof
• Compute the total area
• The estimated cost of the roofing project is equal to: total area * 2.50
• Print out the total area
• Print out the total estimated cost

Hint - The roofs are rectangular

Instructions:

• Construct a list of Mathematician objects
• Print out nice display string of each item in the list

Hint - You may call a method that generates the list for you (if one is available).

Given:

First Name	Last Name	Country	Gender	Known For
Isabel	Hubard	Mexico	F	Symmetries of Combinatorial Objects

Instructions:

• Construct the relevant object for the given data
• Print out only the last name, gender, and knownFor

In hydraulics (flow) the hydraulic radius (r) is a factor that determines the capacity of a channel.

A higher r value means more flow in the channel. This means that two channels may have the same cross sectional area, but one will be more efficient (per higher r).

r = area / perimeter

Given:

Channel Label	Channel Width	Channel Depth
Channel #1	10	10
Channel #2	100	1

Instructions:

• Construct objects for the given data
• Print out the objects
• Print out the label (derived from the objects) of the object that yields more flow in the channel (higher r)
• You may use divide (/) operators in this problem

Hint - The channel is rectangular

Given:

Boundary Left	Boundary Top	Boundary Width	Boundary Height
-3.12	11.11	3.72	6.26

Instructions:

• Construct a Rectangle to represent the given boundary data
• Generate a list using the City newSampleSet1() method
• Iterate through the list of cities
• For each city print out a nice display string, and whether or not (true/false) the given city is inside the boundary

Fun Fact: The boundary above is an rectangular approximation of Ghana.

Given:

City	Country	Latitude	Longitude
Minneapolis	U.S.	44.977753	-93.265015
Accra	Ghana	5.6037	-0.1870

Instructions:

• Construct City objects from the given data
• Compute the distance between the cities (by using various methods in the method menus)
• Print out the distance

Hint - See highlighted message at top of GeoLocation method menu (and note the ivar location on City).

Given:

City	Country	Latitude	Longitude
Accra	Ghana	5.6037	-0.1870
Cairo	Egypt	30.0561	31.2394

Instructions:

• Construct City objects from the given data
• Compute the distance between the cities (by using various methods in the method menus)
• Print out the distance

Hint - See highlighted message at top of GeoLocation method menu (and note the ivar location on City).
