Explain your reasoning. 12. A right circular cylinder fits tightly inside a right regular hexagonal prism so
that each base edge of the prism is tangent to the base of the cylinder. If the
radius of the hexagon base is 8, and the height of the cylinder/prism is 10 cm, find
the volume of the space outside the cylinder but inside the prism, to the nearest
tenth.

i got 10.28 but that rounds up to 10.3

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.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
