Answer 1

D.

Explanation:

(:

Answer 2

Answer: D. 0.6

Explanation:

When the two cones are similar the corresponding radius and heights are in the same proportion,

Thus, By the given figure,

Two cones having radius 3 and x and having heights 10 and 2 respectively are similar.

So, We can write,

`(10)/(2) = (3)/(x)`

`10 x = 2* 3`

`10 x = 6`

`x = 0.6`

Thus, Option D is correct.
