Area, Tennessee, & Parallelograms:)

Well, today, April 18th, I learned about how to find the area of a parallelogram. It is------> A=B*H or A=L*W. These are formulas that would be used for parallelograms and rectangles. Why? Because a rectangle is a parallelogram, right? Right! Now on to a new topic...Tennessee! What is the area of Tennessee?  Wellllllll, the length is about 440 miles and the width is about 120 miles...according to Google. So, times those numbers together and it equals = 52,800. And the actual area is...(drum role please).........42,181! Yeah, they are not the same but, close enough.

Freshman Geometry CHPT.10

In geometry class we have been learning about Chapter 10 (circles). So far I have learned about various segments and formulas. I've learned about radius, chords, and diameters. Formulas I have learned about are C=pi x d / C=2pi x r  <----which are to help find the circumference of a circle. I also learned about different kinds of arcs such as, minor arcs, major arcs, and semicircles. Theorems of chapter 10 are also important to know because it helps you determine how to solve a certain problem about certain circles. Very important! Careers where we can use these certain methods can be astronomy,because of the planets being circular and trying to find the possible circumference of that planet. And last, but not least, a question----->Is the same formula used to find two secants, secant-tangent, and two tangents??
