Answer:
for 9, the answer is 246.49
Step-by-step explanation:
This is area of a circle correct?
The formula is PI x radius squared.
3.14 x the radius, which is 5, squared
I am re-editing this
so sorry the answer is actually 78.54
The reason why it is 78.54 is that you need to square the radius before multiplying with PI.
Look at the table for each type of bird. 5x=15. 6x=18. 10x=30. What would you multiply each of those by to get your answer and find the difference? 5x=15; x= 3. It is the same for each number. So the difference is by 3. I think if I understand this correctly, that would be how you do it. Does this help?
the reasonable estimate is 154
F(x) = 3 * (-4)^n
f(15) = 3 * (-4)^15
f(15) = 3(-<span>1073741824)
