Step-by-step explanation:
<u>650 cannonballs
</u>
Explanation step by step:
layer 12 is 12 ^ 2
<u>The formula is:
</u>
n * (n + 1) * (2n + 1) / 6
n = 12
12 (12 + 1) (2 * 12 + 1) / 6
12 * 13 * 25/6 =
650
<u>There are 650 cannonballs in this pyramid.</u>
Yes.
It's a proportional relationship because when graphing this problem on the graph the line goes through (0,0). Therefor it is a proportional relationship. Some problems like these won't be a proportional relationship because it's not going through (0,0).
