The correct answer is 0.8 in....


The volume of a sphere is calculated through the equation,                             V = 4πr³/3 Which means that the radius is calculated by the equation,                                  (3V/4π)^(1/3) = r Substituting,             Sphere A,       (3x30/4π)^(1/3) = r = 1.927 in             Sphere B,        (3x10/4π)^(1/3) = r = 1.336 in When we subtract the radius, we get an answer of 0.59 inch. Therefore, the answer to this item is approximately 0.6 inch.
