Step-by-step explanation:
First let's find the volume of the sphere, using the following equation:

The radius is half the diameter, so the radius is 14/2 = 7 inches
Now, finding the volume, we have:


Now, we know that we need to have 1 goldfish for every 693 in3 of water, so to find the number of goldfishes, we just need to divide the volume of the sphere by 693 (and round down the result if needed):

Answer:
3rd option
Step-by-step explanation:
Given z is inversely proportional to (y - 2)² then the equation relating them is
z =
← k is the constant of proportion
To find k use the condition when y = 5, z = 9 , then
9 =
=
=
( multiply both sides by 9 )
81 = k
z =
← equation of proportion
