<h3>What are cations and anions?</h3>
When the atom loses the election then it is called a cation and when it gains the electron is called an anion.
Two reactions are given.
First reaction;
Au³⁺ + 3e⁻ ⇒ Au
In the first reaction, Gold (Au) gets 3 electrons and became Gold.
Second reaction;
2I⁻ ⇒ I₂ + 2e⁻
In the second reaction, Iodine (I) loses 2 electrons and became Iodine.

Answer:
310.86ft²
Step-by-step explanation:
30/2 = 15
3.14*15² = 706.5
30+3+3 = 36
36/2 = 18
3.14*18² = 1017.36
1017.36 - 706.5 = 310.86
