Answer:
578 cm^2
Step-by-step explanation:
The surface area is given by one circle of radius 4 (the other is missing!), plus a "rectangle" (the lateral surface) of sides 21 and 
(the length of the circumference at the base). Adding them up we get:
ANSWER: Company C
EXPLANATION:
1) Find the least common multiple of 6, 10 and 12. This would be 60 because:
6 x 10 = 60
10 x 6 = 60
12 x 5 = 60
2) Now you can figure out how much money each company gives for every $60 worth of gift wrap by multiplying the amount they gave in the paragraph by the same as what you did in the calculations above.
<u>Company A</u>
$1 x 10 = $10 for every $60 worth of gift wrap sold
<u>Company B</u>
$2 x 6 = $12 for every $60 worth of gift wrap sold
<u>Company C </u>
$3 x 5 = $15 for every $60 worth of gift wrap sold
ARGUMENT
Company C should be selected because they give the most money per dollar ($15 per $60 worth of gift wrap sold).
I'm not 100% but I got x=-3/2
$19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8
$15.50-$8=$7.50
Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50
