Answer:
Sample size is 
Step-by-step explanation:
Given that,
Margin of error
%
Confidence level
%
Suppose, sample proportion
i.e. 
We know that,
Margin of error 
∴ 





squaring on both side,
∴ 
Hence, the sample size is,

Hence, the correct option is 
<span>ratio of surface area = 49:100
ratio of corresponding lengths = √49:√100 = 7:10
answer: C
Hope this helps
