An action movie production team needs glass spheres to hold a green liquid that looks like an explosive. if all of the available 3,392.92 cubic inches of the liquid is to be poured into 30 glass spheres, what should the diameter of each sphere be? assume that each sphere is filled to the top.
3 inches
4 inches
6 inches
8 inches
9 inches

We are given the total volume of liquid equal to 3392.92 cubic inches and a total of 30 glass spheres to be poured in. In this case, we divide the volume by 30 equal to 113.0973 cubic inches. The formula of the volume of a sphere is 4/3 pi r^3. r then is equal to 3 inches in which the diameter should be 6 inches. 

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
