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.
To find the area of the paper. You must multiply the width and the height, which is 9 and 19.
9 x 19 is 171
And multiply that by 4
171 x 4 = 684
Total area is 684
