Answer:
4960?
Step-by-step explanation:
31 times 160 = 4960
Answer: Volume of an oblique cylinder is 2011.43 sq.m.
Step-by-step explanation:
Since we have given that
Radius of a cylinder = 8 meters
Height of a cylinder = 10 meters
Cavelieri's Principle states that volume of an oblique cylinder is same as the volume of right circular cylinder with equal radius and height.
As we know the formula for "Volume of cylinder":
![Volume=\pi r^2h\\\\V=\frac{22}{7}\times 8\times 8\times10\\\\V=\frac{14080}{7}\\\\V=2011.43](https://tex.z-dn.net/?f=Volume%3D%5Cpi%20r%5E2h%5C%5C%5C%5CV%3D%5Cfrac%7B22%7D%7B7%7D%5Ctimes%208%5Ctimes%208%5Ctimes10%5C%5C%5C%5CV%3D%5Cfrac%7B14080%7D%7B7%7D%5C%5C%5C%5CV%3D2011.43)
Hence, Volume of an oblique cylinder is 2011.43 sq.m.
The area is length x width which means it would be 14 x 8
14 x 8 = 112 so the area of the rectangle is 112 square ft.
Answer:
a) true
Step-by-step explanation:
Decision Rule
If;
P-value > significance level --- accept Null hypothesis
P-value < significance level --- reject Null hypothesis
Z score > Z(at 95% confidence interval) ---- reject Null hypothesis
Z score < Z(at 95% confidence interval) ------ accept Null hypothesis
For the case above, the p-value for the test is 0.047 which is less than the significance level 0.05
P-value < 0.05
Using the decision rule, we will reject the Null hypothesis which is the same as stated in the question, which means its true.
_Confirmed._
