Solve Solve
a cylinder of radius r cm and height h cm has a curved surface area A cm, where
a) obtain a formula for h
b) find the value of h when A = 93 ,R = 2.5 and = 3.1

A cylinder of radius r cm and height h cm has a curved surface area A cm². Where –

a) We are asked to find formula for h.

First, overturn the equation

Divide both sides by 2πr

b) Again, we are given –

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.  

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
