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?

6 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 (20/2)^3

v = 4/3 x π x (10)^3 = 4,188.79 in3

Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.

4,188-79 / 693 = 6.04 = 6 fishes

Feel free to ask for more if needed or if you did not understand something.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: 4 (:
