Answer 4

Okay so the volume of a sphere is shown as
\[\large V= \frac{4}{3} \pi r^3 \]
The diameter is given as 20 in, to get the radius, just halve it, so r= 10 in
\[\large V = \frac{4}{3} \pi (10)^3 \]

Giving you
\[\large V= 4188.80 in^3 \]

To get the number of goldfish, just divide by the 693 in recommended.

Answer 5

So
\[\large \frac{ 4188.80}{693} = 6.0 fish\]
