The value of x is 0.6 if the two cones are a similar option (C) 0.6 is correct.
It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.
[tex]\rm V=\pi r^2\dfrac{h}{3}[/tex]
We have two cones shown in the picture.
The two cones are similar:
Then,
10/2 = 3/x
5 = 3/x
x = 3/5
x = 0.6
Thus, the value of x is 0.6 if the two cones are a similar option (C) 0.6 is correct.
