Tyler is building a fish tank in the shape of a sphere that has a diameter of 18 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? Numerical Answers Expected! Answer for Blank 1:

Answer: 4 fishes

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a sphere = 4/3 x π x (diameter/2) ^3

Replacing with the values given:

V = 4/3 x π x (18/2) ^3

v = 4/3 x π x (9) ^3 = 3,053.63 in3

Next, we have to divide the volume of the tank by 693 in3 (volume for each fish)

3,053.63/693 = 4.40 = 4 fishes
