Question

The two cones below are similar what is the value of x?

Answer 1

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,

$\frac{10}{2} = \frac{3}{x}$

$10 x = 2\times 3$

$10 x = 6$

$x = 0.6$

Thus, Option D is correct.
