The scale factor is 
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

Like wise the ration of height of large cylinder (H) to that of the smaller cylinder (h) is

The scale factor is 
Answer:
x=180-x

Step-by-step explanation:
Answer:
4
Step-by-step explanation:
- represent the number he thought of with x

- multiply through with the LCM which is 2






So h is 3x
b is x
3x plus x equal 972
4x = 972
243 is base
243 times 3 is 729
