Answer:
The total area for all 16 hamburgers is 113.04 in².
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:
[tex]Radius\ (r)=\frac{Diameter}{2} =\frac{3}{2} =1.5\ in.[/tex]
Now, to get the area of a hamburger we put formula:
(Taking the value of π = 3.14.)
[tex]Area=\pi r^2\\\\Area=3.14\times (1.5)^2\\\\Area=3.14\times 2.25\\\\Area=7.065\ in^2.[/tex]
Now. to get the total area of 16 hamburgers by multiplying 16 by the area of a hamburger:
[tex]7.065\times 16\\\\=113.04\ in^2.[/tex]
Therefore, the total area for all 16 hamburgers is 113.04 in².
