Question

Chris made hamburgers for his family and they each had a diameter of 3 in. If he made 16 hamburgers.

What is the total area for all 16?​

Answer 1

The total area for all 16 hamburgers is 113.04 in².

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:

`Radius\ (r)=(Diameter)/(2) =(3)/(2) =1.5\ in.`

Now, to get the area of a hamburger we put formula:

(Taking the value of π = 3.14.)

`Area=\pi r^2\\\\Area=3.14* (1.5)^2\\\\Area=3.14* 2.25\\\\Area=7.065\ in^2.`

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

`7.065* 16\\\\=113.04\ in^2.`

Therefore, the total area for all 16 hamburgers is 113.04 in².
