Depends on diameter and radius.
1. If the diameter of the ocean ball is 8 cm, then the radius r = 4 cm, the area of the circle S = πrr and S = 1000*3.14*4*4=50240, so the ocean ball occupies an area of 50,240 square centimeters.
2. If the radius of the ocean ball is 8 cm, then S=1000*3.14*8*8=200930, so the ocean ball occupies an area of 200930 square centimeters.
