E I think I am not sure though.
Answer:
it is what it is take a guess
Step-by-step explanation:
An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.
Perimeter is adding all sides so the answer will be 12(pi) + 46, hope this helps!!
