Answer:

Tyler should buy 4 fishes

Explanation:

diameter d of Tyler's sphere tank = 18 inches

radius r of the tank = d/2 = 18/2 = 9 inches

Volume of water that will be contained within the sphere will be roughly equal to the volume of the sphere

Volume of a sphere = [tex]\frac{4}{3} \pi r^{3}[/tex]

Volume of the sphere = [tex]\frac{4}{3}*3.142*9^{3}[/tex] = 3054.024 cubic inches

since it is recommended to have no more than 1 goldfish for every 693 cubic inches of water,

number of goldfishes will be = 3054.024/693 = 4.41

since there can only be a whole number of goldfishes, then,

Tyler should buy 4 fishes
