Compare and Contrast
Prisms and pyramids have the exact same volume as a prism except that it is 1/3 of the entire thing. Cylinders and cone are also similar this way in volume the cone is 1/3 of the cylinder. Surface area is another story because on a prism you add all of the sides, on a pyrimid all you have to do is find lateral area and add the are of the base. A cone is the same formula as the pyramid, but a cylinder is 2pi*r sq+2pi*r*h.

parallelogram homework
The formula of parallelograms and squares is the same because they have similar dimension structures so the formula works for both.
length of Tennessee is 430 mi. 430*110= 47,300
width 110
area- 47300 mi.
Actual area 42,144 sq. mi.

Paragraph
I have learned what inscribed angles are and how to find them. I have also learned about central angles and how they equal their arc.I have learned about minor arcs, major arcs, and semicircles. Lastly, I have learned about secants and how to solve them using tangency lines.
