Answer:
There are 8 boys for every 10 girls. This is 6 equal groups. Equal ratio
Step-by-step explanation:
The total length of the circle is calculated by the following formula:
Lenght = 2.π.r
As r = 4c
Then,
Lenght = 2.π.4
Lenght = 8π centimetrs
Now use the rule of 3
But we have to know:
...<..> ...
Then,
8π ________ 2π <= 360°
x ________ 3π
2π . x = 8π . 3π
x = (8π . 3π) / 2π
x = (8 . 3π)/ 2
x = 12π centimenters
x ~ 37,69 c
I believe this is called scaling. This is the word that I am associating with your definition, as well as what many internet sources say. I am not 100% sure, but I think this is correct. Hope this helps.
