Question: Use the formula A = x for the surface area A of a sphere whose diameter measures d. This formula yields the surface area

Use the formula A = x for the surface area A of a sphere whose diameter measures d. This formula yields the surface area in square units. The Hoberman Sphere is a mechanical toy that expands from 5.9 inches in diameter when it is fully closed, to 30.1 inches diameter when fully expanded. What is the difference in the surface area of a Hoberman sphere from when it is fully clos when it is fully expanded (in in)? Round the result to three decimal places.
