<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>
5 and 7/10, 5.749, 5.78, and then 113/20
Answer: the product is = 33+4i
Step-by-step explanation:
21+4i-12i^2
21+4i-12(-1) i^2=-1
21+4i+12
your answer would be 33+4i .
