Answer:
The scale factor is [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Yes the figures are similar to each other. The ratio of their linear measurements is in uniform ration
The ration of radius of large cylinder (R) to that of the smaller cylinder (r) is
[tex]\frac{18}{12} \\\frac{3}{2}[/tex]
Like wise the ration of height of large cylinder (H) to that of the smaller cylinder (h) is
[tex]\frac{30}{20} \\\frac{3}{2}[/tex]
The scale factor is [tex]\frac{3}{2}[/tex]
