Answer:
1/6 ton of fish is provided during the night feeding.
Step-by-step explanation:
The fish consumed in the morning is
tons, and the amount of fish served in the afternoon is
greater than in the morning. This means

Let’s represent the quantity of fish given at night as
, and if the total fish fed throughout the day equals
, we have

By summing the numerators on the left side, we derive:

and subtracting
from both sides allows us to isolate 

Since
, we derive

The common denominator for the fractions is 6; hence, we write the equation in the form

and simplifying the numerators results in:

which indicates the amount of tons fed during the night feeding.
Initially, you must determine the circle's circumference since one complete rotation corresponds to one length of the circumference. The formula to calculate circumference is C=2πr or C=πd; for a diameter of 1 meter, the circumference equals π1, which is simply π. Therefore, if it makes 8000 rotations, the distance traveled would be 8000π meters.
