Work out the area of this circle. Take a to be 3.142 and give your answer to 2 decimal places.
9 m​

Area of a circle = 3.14 X radius X radius

= 3.14 X 4.5 X 4.5 = 63.585 m2

Hope this helps

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.
