The volume of a cone is V= (1/3)pi r²h
it was given
h=12cm
radius=3cm
the volume of the first cone is V1= 1/3)pi r²h1
where h1= h/2=6cm
so its volume is V1=1/3)xpix3²x6=56.52cm^3
and since the two cones are identical so V1=V2=<span>56.52cm^3,
we need </span><span>56.52cm^3 or salt </span>
Answer: B. 
Step-by-step explanation:
The confidence interval for the population mean is given by :-

Given : Sample size : n= 100
Sample mean : 
Standard deviation: 
Level of confidence = 0.95
Significance level : 
Critical value : 
Then, 95% confidence interval for the population mean will be :-
