Answer:

The total volume of juice in a six-pack is $254.3\ in^{2}$

Step-by-step explanation:

step 1

Find the volume of one can

The volume of the cylinder (can of juice) is

$V=\pi r^{2} h$

we have

$r=3/2=1.5\ in$ ----> the radius is half the diameter

$h=6\ in$

assume

$\pi =3.14$

substitute

$V=(3.14)(1.5)^{2} (6)$

$V=42.39\ in^{2}$

step 2

Find the total volume of juice in a six-pack

Multiply the volume of one can by 6

$42.39*(6)=254.3\ in^{2}$

I will give 10 pt to who ever answer the question

OK, because it is asking you to subtract a (negative) number and two negatives make a positive, the question would be -56 + 27.07 = ? with some simple addition, the answer would be <span>-28.93.

I hope this helps :)</span>
