You are decorating a clean soup can to make a pencil holder. you are going to glue yarn around the top and bottom of the can. the total amout of (y) yarn in inches (in inches) you need is given by the equation y = 4πr where r is the radius of the can. solve for r. i will give brainliest

r = y / (4π)  

37.68 = 4 x 3.14 x r  

37.68 = 12.56 r  

so r = 37.68 ÷ 12.56 = 3

Step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
