A drum has a diameter of 16 inches. Find the area of the top of the drum. Round to two decimal places. Use 3.14 for π.

d = 16 in.

The area of the top of the drum is about
in2.

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.
