Ch. 23-25 Test Review

You should be able to:
1. Determine the range of measurements given the measuring tool's limitations.
2. Convert metric measures to larger and smaller metric measures. (i.e convert km to m)
3. Determine the number of degrees in a partial circle if the ratio is known. (i.e. 15 minutes on a clock face would have how many degrees?)
4. Be able to convert between different square measurements, i.e., sq cm to sq meters
5. Determine the area of an unusual region on a Geoboard (square dot paper)
6. Determine scale factors and use them to find surface area or volume of a similar figure.
7. Given corresponding lengths of two similar objects, be able to calculate the ratio of their surface areas and their volumes (the surface area and volume factors).
8. Know how to find missing lengths (i.e. leg of right triangle, diameter & radii of a circle, perimeter, circumference), and find area of polynomials (may need to memorize formulas).
