Surface Area and Volume

Prisms and Pyramids are similar because their surface area formulas are somewhat alike. A prism's formula for surface area is mainly finding the base times the height. A pyramid's formula is the base times the height divided by three. The only difference between the two is the pyramid is divided by three. A cylinder and cone are also alike is some ways. A cylinder's surface area formula is 2 x 3.14 x the radius squared + 2 x 3.14 x the radius x the height. A cone's surface area formula is S=L+B; however before finding the surface area you must find the lateral area of each side, using L= 3.14 x the radius x the length. This is how these figures are alike and different because their surface area formulas are almost the same but not exactly. The prims' and pyramids' volume formula are not alike. The prism has many different volume formulas, such as cube= s cubed, rectangular= l x wx h, and V= b x h. The pyramid's volume formula is just V= b x h divided by three. The cylinders and cones are alike except for the cone is divided by three. These are the differences and similarities of prims, pyramids, cones, and cylinders.

Annabella Milbanke

Annabella Milbanke was a very smart child. She loved learning. In order to show her intelligence, her parents hired a student from Cambridge University to go more in depth with her studies. Annabella's favorite subjects were: literature, philosophy, science, and most of all mathematics. Her fascination with mathematics led her husband, Lord Byron, to call her his "Princess of Parallelograms".

Area of Tennessee

The formula for a rectangle, square, and parrllelogram is not different because the dimensions and measurements may stay the same; however, the shapes can be formed differently. The dimensions of Tennessee is 430 miles East to West and 110 miles North to South. These dimensions making Tennessee have an area of 47,300. But the actual area of Tennessee is 42,144.

Chapter 10

In Chapter 10, I have learned many things. One, I learned how to solve inscribed circles. Two, I have also learned how to solve secant and tangent circles. A job that includes circles would be a waitor or waitress because their job includes serving circular tables. One question I have while learning chapter 10 would be: how do I determine each type of secant circle?
