The total area for all 16 hamburgers is <u>113.04 in²</u>.
Step-by-step explanation:
Given:
Chris made hamburgers for his family and they each had a diameter of 3 in.
If he made 16 hamburgers.
Now, to find the total area for all 16 hamburgers.
So, the diameter 3 in is given and we need first to find the radius:

Now, to get the area of a hamburger we put formula:
<u><em>(Taking the value of π = 3.14.)</em></u>

Now. to get the total area of 16 hamburgers by multiplying 16 by the area of a hamburger:

Therefore, the total area for all 16 hamburgers is 113.04 in².
Answer:
Step-by-step explanation:
Let the number of hours Nick does the job alone to be x - 3 hours
Hence, in 1 hour, Nick has done 1/x - 3
Together they complete the job in 9 hours
Hence, let's represent the job as 1
9/x + 9/x - 3 = 1
Multiply through by (x)(x-3)
9(x- 3) + 9(x) = 1
9x - 27 + 9x = (x)(x-3)
-27 = x² - 3x
x² - 3x +27 = 0
