Coordinate Grid

Today we took a test where we cut and glue. This test was easy because our group already knew the stuff. After everyone finished the test we learned that a plane is a 2D space. We also tried to figure out how to find the area of a circle. It took us while but then Mr. Sudo just gave us the answer. The way to figure out how to find the area of a circle is to use this formula Acircle = Pie r Exponent 2. He had a question about area of a circle and the answer to that question was 12. That is what we did today.
