The way to find the area of a circle is to find the radius, multiply it by itself, then multiply by pi. The diameter is double the radius so we have to divide the diameter by 2 to find the radius. 31.6/2 is equal to 15.8, and if we plug it into our formula, we can find that the area is 15.8 * 15.8 * pi, and since we use 3.14 for pi, the area is 15.8 * 15.8 * 3.14. We can use a calculator for this part and find that the area of this circle is 783.8696.
A) 60 Clown fish / 5 = 12 12 x 4 = 28 Angel fish B) 28 Angel fish / 4 = 12 12 x 3 = 36 Gold fish C) Add all fish 28 Angel fish + 36 Gold fish + 60 Clown fish = 124 Fish in total
