Answer: D. 0.6
Step-by-step 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,
[tex]\frac{10}{2} = \frac{3}{x}[/tex]
[tex]10 x = 2\times 3[/tex]
[tex]10 x = 6[/tex]
[tex]x = 0.6[/tex]
Thus, Option D is correct.
