We know that volume and surface of a sphere if its radius is r is given by, Volume of sphere = (4 / 3) π r 3 . Surface area of sphere = 4 π r 2. We have to find the value of A / V. Hence, A / V = (4 π r 2) ÷ (4 / 3) π r 3 = 3 / r. Hence, for a sphere of radius r, the ratio of surface area to volume is 3 / r..

1. Calculate the surface area of the following: 1) the portion of the sphere x2 +y2 +z2 = 16z x 2 + y 2 + z 2 = 16 z that lies within the paraboloid z =x2 +y2 z = x 2 + y 2. Attempt:so by rearranging the eqn given we have a sphere with centre …
