Height of a cone is 30cm, its slant height is 32 cm, then the radius is- ?

Given:

Height of a cone is 30cm, its slant height is 34 cm.

To find:

The radius of the cone.

Solution:

Using the Pythagoras theorem, the relation between Height, radius and slant height is

Where, r is radius, h is height and l is the slant height.

Putting the given values, we get

Taking square root on both sides.

Radius cannot be negative. So, r=16 cm.

Therefore, the correct option is b.

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.
