Math regents questions

hey, I am trying to solve it, and its actually pretty easy.
Here wew go:
Volume of sphere = (4/3)*pi*r^3
density= m/v

Find out how many grams of aluminium atoms make up 8.55* 10^22 atoms, and then solve this through substitution. oK?

yeah but this is a semi circle ... aka half a circle ... so you're gonna divide it by 2 anyway ...
