27$ because you do 20*15*12 then 3600*0.09 and divide that answer by 12 which is 27
The answer is: I don't really know. YOU DIDN'T GIVE A SIDE SO BOW AM I SUPPOSED TO KNOW!!!!!!!!!!!!!!!!!!!!!!
You have to give a side first.
The area of a circle is given by

If you want to approximate pi with 3.14, the formula becomes

Answer:
240
Step-by-step explanation:
We need to find the coeffeicent of the binomial expansion of

Note that

The binomial theorem states that

Using this, we let expand our series


So what term in the series eqaul x^-5.
That term is the 10 choose 7 term.

Because

So we need to compute 10 choose 7.
That equals
10!/3!(7!)= 10×9×8/6= 720/6=120.
So we get


So the coeffceint u
is 240
