Answer:
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:
200.96
Step-by-step explanation:
A = πr²
A = 3.14 x 8²
A = 3.14 x 64
A = 200.96
3180 because you divide 31800 by 10
Answer:
Step-by-step explanation:2 and 4
