Area of a circle Investigation

Area, Circle
Step 1: Draw the radius squares. Step 2: What is the area of each radius square? Step 3: Before filling in each area of the quarter circles, estimate how many square units fill that space. Check your estimate by clicking the "fill area" box when you're ready. Step 4: Explore- how many radius squares fill the entire circle? Drag the outer areas of the radius squares into the white section of the circle. Try not to overlap pieces.
