Pls pls help! super desperate. find the lateral surface areas of the shapes shown in the photo

3- 0.14   2- 841

Step-by-step explanation:

3- 0.7*0.2=0.14

2- 56/2= 28

   28*28+29*29= 841*841

   square root of 841*841= 841

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.  

i think it might be a but you might want a second opinion
