Below is the solution:

10:4 = 6:x

10x = 24 
x = 2.4

Answer 2

The given cones are similar .Similar figures have sides in proportion.

Forming the proportion for similar sides in the two cones we have:

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

This is of the form :$\frac{a}{b} = \frac{c}{d}.$

We can cross multiply.

Cross multiplying we have:

10x=9

Dividing both sides by 10 we have

x=$\frac{9}{10}.$

x=0.90.
