Comparing and contrasting volume and surface area!

Prisms, pyramids, cones, and cylinders all have different, yet similar formulas when it comes to finding the volume and surface area of them. Lets take a look at them.

Cylinders:
SA= 2(pi * radius squared*) + 2* pi*radius* height
V= pi*radius squared* height

Cones:
SA=  Lateral area plus the area of the base....L+B.
V= 1/3* pi* radius squared* height

These formulas for volume are similar because they are both being multiplied by radius squared and the height. The difference in them is that the volume of a cone has to be divided by 3.

Prisms:
SA= Two times the area of the base plus the base's perimeter times the height...2b+bh.
V=  The area of the base times the height

Pyramids:
SA= L+B....Lateral area plus the area of the base
V= 1/3 times the base and the height

These formulas are again similar in volume, in that the both multiply the base by the height. The difference in these is that the pyramid divides the base and height by 3.

Have a GREAT day!

The Princess of Parallelograms

Anne Isabelle Milbanke is not a very ordinary name to begin with. Try being called the "Princess of Parallelograms." Now, I know what your thinking, but theres a perfectly logical explanation to this name. Before Anne and her husband divorced after very little time, he saw that she had a passion for mathematics. Thus, he decided to nickname her the "Princess of Parallelograms" which is soon what she became known as. Her ex husband moved away and left Anne and her daughter Ava. He died eight years later in Greece.
Have a great day!

Area Formula for Rectangles and Parallelograms!

In case this never crossed your mind, the area formula for rectangles and parallelograms are the same! It is a simple formula, it looks like this: A=bh or A=lw. This formula just multiplies the base and the height, thus telling the area of the shape. How are the formulas the same you ask? Well, both the shapes can be turned into each other by cutting the sides or something like that. Therefore, since they are the same shapes in the end, the same formula can be used!

Continuing on, the dimensions of Tennessee were asked to be learned as well. By the information gathered from netstate.com, Tennessee is 440 miles long and 120 miles wide. Now, by using the formula from the first paragraph, it will look like this: A of Tennessee= (440)(120). The estimated area would come out to be approximately 53,00 miles. Have a nice day!

What I've Learned from Ch. 10.

1.So far, I have learned all about circles. I have learned how to find the angles,arcs,and chords of them. Also, I now know how to find all the angles in an inscribed and circumscribed circle. I just recently learned how to find tangents and secants. They are a little more challenging to do if you ask me.

2. Meteorologists, archtects, and engineers are some examples of people who use angles of light on a day to day bases to determine things.

3.  I am having a little trouble with the secants and tangent angles in 10-6. How do you find the measure of a arc or angle using secants?

Have a nice day!:)
