Last week we began studying perimeter, circumference, and area. We began by looking at the new 7th grade STAAR formula chart. There have been some very interesting changes. Students need to be able to use this page as a tool. It can be used for measurement (area, volume, and surface area) and also ratio and proportion with unit conversions.
This week we will continue our lesson from Thursday over circumference and area of circles. This seems to be a big topic this year so we will be hitting it hard. Tuesday and Wednesday we will be looking at irregular or composite figures. This is where you may have to find the area of several shapes and add them together. Thursday we will work on a test review for a test over area on Friday.
Bonus Question of the week:
Copy the question, solve and turn it in by Friday, Feb. 6th.
A pizza of diameter 16 inches has an area large enough to serve 4 people. What is the
diameter of a pizza with an area large enough to serve 12 people? Express your answer as
a decimal to the nearest tenth.
