Week 7: Circles and Curved Objects

This was a very exciting week, because we finally got to think outside the box! Now that we covered pretty much every angle of polygons and polyhedra, we were able to dig into circles, spheres, and other curved figures. Use this link for reviewing circle stuff, and check out this link for spheres and other objects.

For this week's assignment, you will have to do a little bit of research. Also, it will be broken into two parts involving Earth. The first part is to find the surface area and volume of the Earth using the distance from the center of the Earth to the equator (and assuming the Earth is a perfect sphere). The second part is to list at least 3 famous cities and find the angle from our city to those cities.

Remember, with a sphere you need to find both the latitude and longitude angles. I'll always be willing to answer any and all questions, so if you feel lost or confused then don't feel alone! I can point you in the right direction.

This week's goal:

• Become familiar with the process of the system of global coordinates
• Practice and recognize formulas for circles and spheres

 Due date:

• Hand in work and the angles to other cities by the next test day (which will be decided on in two weeks)
