PLEASE HELP AREA AND CIRCUMFERENCE OF A CIRCLE

Area:  200.96 cm

Circumference:  50.24 cm

Explanation: I recently just learned this.  The area of a circle is Pi times radius squared which makes.  3.14 x 8^2 = 3.14 x 64 = 200.96.  SInce none of the original measurements are squared it will be    200.96 cm

The circumference of a circle is diameter times pi which makes  3.14 x (8 x 2) = 3.14 x 16 = 50.24.  Since none of the original measurements are squared it will be 50.24 cm

I hope this helps!  pls mark brainliest if it helps!

A=200.96cm²

C=50.24cm

Step-by-step explanation:

A=πr²=π·8²=200.96

C=2πr=2·π·8=50.24

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.
