Option B

Amount of orange juice did Fabian use to make the punch is 11 liter.              

Step-by-step explanation:

Given : Fabian mixes orange juice with 4 cans of pineapple juice to make punch. Each can of pineapple juice holds 2 liters. He makes a total of 19 liters of punch.

To find : How many liters of orange juice did Fabian use to make the punch?

Solution :

Let x be the amount of orange juice.

There are 4 cans of pineapple juice.

Each can of pineapple juice holds 2 liters.

So, 4 cans can hold liter of pineapple juice.

Together they make x+8 liter.

He makes a total of 19 liters of punch.

i.e.

Therefore, Amount of orange juice did Fabian use to make the punch is 11 liter.

So, Option B is correct.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
