Well pie is 3.14 etc.
And the way to find that out is by:
~Using the formula.
~To find out what the circumference is you have to use this formula<span>
C= π*d =2*π*r
</span>~Pi<span> equals a circle's circumference divided by its diameter.
</span>~If you plug in the numbers in a calculator the numbers should be 3.14.
Lila did it correctly. The answer is 324
Following PEMDAS, we first focus on the parenthesis. So we simplify 9-3 to get 6
So we go from
18*4^2+(9-3)^2
to
18*4^2+6^2
The next step is applying exponents. In this case, squaring the terms, so we go from
18*4^2+6^2
to
18*16+36
Next is multiplying
18*16+36
turns into
288+36
Finally, add up 288 and 36 to get 288+36 = 324
That confirms that Lila is correct
----------------------
The error that Rob made is that he computed 18*4^2+9^2-3^2 but it is NOT correct. Saying (x-y)^2 = x^2-y^2 isn't a true equation for all x and y. Again you have to simplify what is in the parenthesis first, and then you can square it. Or you must use the FOIL rule to expand out (9-3)^2

Answer:
<em>4 shelves</em>
Step-by-step explanation:
First you will have to subtract the one she keeps by her bed.
27 - 1 = 26 to be put on a shelf.
To find the least number of shelves needed, you will divided the total left by eight:
26 ÷ 8 = 3.25
She can fill 3 shelves completely and still have books left over. So she needs at least 4 shelves!
