Answer: 27:1
Step-by-step explanation:
We know that the volume of cylinder is given by :-
[tex]V=\pi r^2 h[/tex], where r is radius and h is height of the cylinder.
Also, If two figures are similar then ratio of volume is equal to the cube of any dimension .
The ratio of the volume of Pipe A to the volume of Pipe B is given by :-
[tex]\dfrac{V(A)}{V(B)}=\dfrac{6^3}{2^3}=\dfrac{27}{1}[/tex]
Hence, the ratio of the volume of Pipe A to the volume of Pipe B = 27:1
