During this activity, we cut an orange in half, traced the circumference of the oranges about twelve times, and then peeled the orange to determine how many circles the flat orange peels could fully fill, and we ended up with four circles filled. With this information, we determined that the surface area would be the circumference of the sphere multiplied by four. Afterwards, we disposed of everything and cleaned up the mess of oranges.

The formula to find the surface area of the sphere would be 4 multiplied by Pi(Diameter)

Check your formula for Surface Area. I think you used circumference instead of area.
