Sean used candle molds, as shown, to make candles that were perfect cylinders and spheres:
what is the approximate difference in the amount of wax needed to make a candle from each of these molds? use π = 3.14.

18.0 cubic inches
28.26 cubic inches
37.0 cubic inches
56.52 cubic inches

We calculate for the volumes of each of the wax needed for the candles through the equations presented below.

For cylinder:
                             V = πr²h
where V is volume, r is radius and h is height.

Substituting the known values,
 
                           V = (3.14)(3 in)²(6 in)
                            V = 169.56 in³

For sphere:

                         V = 4πr³/3
Substituting the known values,
                        V = 4(3.14)(3 in)³ / 3 = 113.04 in³

The difference between the two volumes,

                         difference of volumes = 169.56 in³ - 113.04 in³
                         difference of volumes = 56.52 in³

Thus, the answer to this item is the last choice.
