The volume of the right circular cylinder is 31064.54 cm³.
What is the formula for the volume of cylinder?
Formula:
V = πr²h.............. Equation 1
Since,
V = Volume of the right circular cylinder
r = radius of the base of the cylinder
h = height of the cylinder.
We have given that,
r = 46.25/2 = 23.125 cm
h = 18.5 cm
π = 3.14
We have to calculate volume of right circular cylinder.
Therefore,
Substitute these values into equation 1
V = 3.14(23.125²)(18.5)
V = 31064.54 cm³
Therefore
The volume of the right circular cylinder is 31064.54 cm³.

Answer:
D. at the ballpark
Step-by-step explanation:
The y-coordinate doesn't change between points C and D. That means Daniel's distance from home is not changing. Since Daniel rode to the ballpark and back, and since segment CD represents Daniel's farthest distance from home, we conclude ...
CD represents the time Daniel spent at the ballpark.
Answer:
We are 95% confident that the true proportion of TV audience is between 65.15% and 65.85%
Step-by-step explanation:
-From the given information,
.
-We calculate the confidence interval using this value at 95% confidence level:
![CI=\hat p\pm z \sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\\\=0.65\pm 1.96\times \sqrt{\frac{0.65\times 0.35}{12000}}\\\\\\=0.65\pm 0.0085\\\\\\=[0.6415,0.6585]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20z%20%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%29%7D%7Bn%7D%7D%5C%5C%5C%5C%5C%5C%3D0.65%5Cpm%201.96%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.65%5Ctimes%200.35%7D%7B12000%7D%7D%5C%5C%5C%5C%5C%5C%3D0.65%5Cpm%200.0085%5C%5C%5C%5C%5C%5C%3D%5B0.6415%2C0.6585%5D)
So, the 95% confidence interval is (0.6515,0.6585).
Hence, we are 95% confident that the true proportion of TV audience is between 65.15% and 65.85%.
