Tyler is building a fish tank in the shape of a sphere that has a diameter of 20 inches. Based on Tyler's research, it is recommended to have no more than 1 goldfish for every 693 cubic inches of water. How many goldfish should Tyler buy for his fish tank?

Question

First step, calculate the radius of the tank by dividing the distemper by 2. Your diameter is 20 inches so simply divide 20/2 to get 10 inches as the radius.

Second, calculate the volume of the sphere as (4/3)pi * r^3 using the radius from before.

Finally, since the limit is 1 goldfish per 693 cubic inches, divide total volume by 693 to get the maximum number of fish. Round down to the nearest whole number since you can only have whole numbers of fish.

*the diameter, not the distemper. Autocorrect.
