What did you do?

For this task we were to cut an orange into hemispheres and then peel the orange. Then we filled as many circles with orange peels as possible. One of our strategies was to peel small pieces so the peels could lay flat and take up more space in the circle. In the end we ended up with 4 full circles.

What did you learn?

I learned the formula to find the SA of a sphere and how to maximize space.

The surface area of a sphere is 4(pi)(r)2 because the formula for one circle would be pir2. We have to multiply because there are 4 full circles filled with orange peels.
