Ms. Batson's surface area and volume comparison

. The surface area of a cone is lateral area + area of base. The volume of a pyramid is 1/3 x lwh because it is one third the volume of a prism. The volume of a cone 1/3 x pi x radius squared x height because it is one third the volume of a cylinder, which is pi x radius squared x height.A pyramid and a prism's surface area are very similar. The surface area of a pyramid is the lateral area plus the area of the base. Then the surface area of a prism is 2(lw+wh+lh). The surface area of a cylinder is 2 x pi x radius squared + 2 x pi x radius x height

The area formulas for a square, rectangle, and parallelogram are the same because they are all parallel quadrilaterals. 
The length of Tennessee is 440 ft, the width is 120 ft, 
and the area based off of that is 52800 ft. 
The actual area of Tennesse is 41220 ft.

Ms. Batson blog homework 1

What I learned from chapter 10 is the different theorums dealing with tangents, and how raidii and diameters help you measure the different side lengths. Also I learned about inscribed angles and how to figure out angles of two raidii. Also, I have learned how to use the pythagorean theorum to solve missing tangent angles.

A job this would be most helpful for, is a construction worker.

Can there be three secant lines?
