You can tell before you divide 387 by 4, that the first digit of the qoutient is going to be in tens place, because 3 can't go into 4.
For this case we have the following polynomial:

To answer the question, what we must do is rewrite the polynomial in its standard form.
We have then that the polynomial will be given by:

Therefore, we have the ordered polynomial in descending form of exponents.
Therefore, the second term of the polynomial is:

Answer:
The second term of the polynomial is given by:

Answer:
I don't know where those answers are coming from, but I got:
23s - 145
Answer:

Step-by-step explanation:
Therefore,
should be your final answer.
The area is 28.26
to find the radius you have to divide the diameter by 2 which you’ll get 3
then plug it into the equation
A=3.14•3^2
