Find the circumference and area of each circle. Include the formula thank you

Circumference: 50.27 cm

Area: 201.06 cm²

Step-by-step explanation:

Hi there!

1) Determine the circumference

where d is the diameter of the circle

Plug in the diameter (16 cm)

Therefore, the circumference is 50.27 cm when rounded to the nearest hundredth.

2) Determine the area

where r is the radius

Plug in the radius (16/2=8)

Therefore, the area of the circle is 201.06 cm² when rounded to the nearest hundredth.

I hope this helps!

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.
