Use the grid to estimate the area of the circle.
diameter of 3 centimeters
area: about
cm?

Given that the diameter of the circle is 3 centimeters.

We need to determine the area of the circle.

Radius of the circle:

The radius of the circle is given by

Thus, the radius of the circle is 1.5 cm

Area of the circle:

The area of the circle can be determined using the formula,

Substituting and , we get;

Thus, the area of the circle is 7.1 cm²

About 28.27

EXPLANATION:

Formula for area of circle is: πr^2

R= 3, given in the question

3^2 = 9

Answer 9 π = about 28.27

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.
