Answer:
The surface area is divided by 4.
Step-by-step explanation:
Surface area of a sphere is 4πr².
When the diameter is 28 the radius is 14. So: 4π(14)² = 784π
If you cut the diameter in half you get 14. The radius is now 7.
4π(7)² = 196π.
784/4 = 196 so divided by 4.
If we slice this down the middle and fit it together like a puzzle we'll get a rectangle base 9.6/2 and height 4.8+9 so area (9.6/2)(4.8+9) = 66.24 square units.
