The figure below shows a cone, with a radius of 9, with the top cut off. The cut-off piece has a radius of 3 and a height of 4. Determine the lateral surface area of the part shown below. Round answer to the nearest hundredth.

2160ft3

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.
