One link in a chain was made from a cylinder that has a radius of 2 cm and a height of 20 cm. how much plastic coating would be needed to coat the surface of the chain link? use 3.14 for π. 251.2cm2 314 cm2 345.4 cm2 471 cm2

answer:

the answer to your question is:

step-by-step explanation: area = 251.2 cm²

data

radius = 2 cm

height = 20 cm

π = 3.14

area

rectangle = base x height

perimeter = 2πr

                = 2(3.14)(2)

                = 12.56 cm

rectangle = (12.56 x 20)

                  = 251.2 cm²

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.
