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

hmmmm........
Step-by-step explanation:
radius is 4/2=2m
volume of the cylinder is equal
to πr^h
i.e, π(2m)^2×7m
≈88 m^3

Answer:
10%
Step-by-step explanation:
We assume the "sum" being referred to in both cases is the principal amount invested. The simple interest formula tells you ...
I = Prt . . . . . . interest on P invested at annual rate r for t years
We have ...
Filling in these values, we get ...
0.3P = Pr(3)
0.1 = r . . . . . . . . divide by 3P
The interest rate is 0.1×100% = 10% per year.
