Trigonometry

Trigonometry is the branch of mathematics dealing with similar planar and spherical triangles. It was originally invented for astronomers to measure distances of stars, planets, etc. Because in that time, astronomy was one of the main fields of science. Trigonometry is used in a variety of jobs. Flight coordinators use it to determine travel through air currents. The height of a tree was 98.9 inches, and the height of the garage was 77.2.

Pringles Can

Here is a list of the dimensions of the Pringles Can:

Lid= 3 in.

Can= 2 15/16 in.

Height= 10 ½ inches

A of pringle= 2.5

Area of circle 6.77

Volume of Can: 22.65

Surface Area of Can: 55.2 in squared

My new container would be a box, and it would have 6 stacks of 13 Pringles, that way it would hold all of the Pringles the can would. I think this is a better choice, because people will have easier access to the chips, than in the can.

Dimensions of new container:

Box Height: 2.5 in

Box length: 3 in

box width: 5 in

Volume of Box. 37.5 in Cubed

Surface area of Box: 70 in squared

My results showed that there is some wasted space in the Pringles can. I think that with my new box, that no space would be wasted. The box would only take up the exact amount of space we would need. This could cut down on costs, and would make the box more compact. That way, people could store it almost anywhere.

The people who design containers should always go through this process. It is a way to make sure the customers get the most convenient product. This also saves the company money. The companies usually like it when they save money. That's why this is important to do.

Area App

Here are the dimensions of each room: Elevator Room: 18.51X5.4, Parallelogram room: 18.73X3.95, Small rectangle: 6.35X3.86, Triangle: 8.1, 17.53, 18.73, Big triangle: 21.93, 23.3, 7.57. The areas and formulas for each of the rooms are: Parallelogram: formula; hb=A, work:18.73x 3.95=73.93 units squared, Elevator room: formula; hb=A, work; 18.51x5.4= 99.95 units squared, Small Rectangle; formula; hb=A work; 6.35x 3.86= 24.51 units squared, Triangle; formula; 1/2bh=A, .5x8.1x17.53= 71 units squared, Big Triangle: formula; .5bh=A, work; .5x7.57x21.93= 83.01. You could use area formulas a lot in home design and remodeling. Maybe, you have a room that is 10 ft. by 12 ft., and you need to know how much space to carpet. Or maybe you need to know how big your bathroom is to know how big of a bathtub to buy. You could need to know how big your bed is so you know what size of bed to buy when you get a new one. floorplan

Irregular figure

1. Area is the amount of space there is inside a figure.
2. I think that it is about 19 cm. squared. My first thought was to count all of the complete squares in the image. Then I pieced them together slowly. If something looked like it was about half of a segment I added that to another about half. I know I won't get the exact size, but I think I'll be pretty close.









3. The area is 10 units squared. For the pond I would think about using feet. For the lake I would use miles.

It is important to know how to do this, because you need to know the area of different places for many jobs. Carpenters, architects, etc. could not do there jobs if they couldn't use this skill. Even pizza places sometimes need to know the area of there pizzas. This skill is needed throughout many industries
