Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height. We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in. Using formula for volume of a cone and plugging in what we know, we have 12 = 1/3*pi*(1.5)^2*h, were solving for h. To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches

Answer:
Option B is right
Step-by-step explanation:
Given that there was a comparison test for two samples done. The differnce between the sample means does not fall within 95% confidence interval.
This means that there is 95% chance that there will be a significant difference between the two means.
Hence whenever we compare two samples, we find the mean difference, margin of error, and confidence interval 95%
Whenever the mean difference does not fall within the confidence interval, we find that the null hypothesis namely that the two means are equal cannot be accepted
Hence option B is true.
Answer:
the first option x = 6sqrt2 y =6
Step-by-step explanation:
if this is special right triangles than this is the 45 45 90 one soo the 45 angles are 6 and the 90 (hypotenuse) will be x (6) with a square root of 2
