Answer:
Volume of the tank = 636 ft³
Step-by-step explanation:
Formula for the volume of a cylinder is,
V = πr²h
Where r = radius of the cylinder
h = height of the cylinder
By substituting the values of radius and height of the water tank given in the question,
V = ![\pi (4.5)^{2}(10)](https://tex.z-dn.net/?f=%5Cpi%20%284.5%29%5E%7B2%7D%2810%29)
= 202.5π
= 202.5 × (3.14)
= 635.85 ft³
≈ 636 ft³
Therefore, volume of the cylindrical water tank is 636 ft³.

(2x-5)(x-2)
Answer:
Step-by-step explanation:
Diameter of the pipe = 6 ft
Therefore, radius (r) = 6/2 = 3 ft
Height of pipe (h) = 32 ft
Since, pipe is cylindrical in shape.
![\therefore \: V_{pipe} =\pi {r}^{2} h \\ \\ \therefore \: V_{pipe} =3.14 {(3)}^{2} (32)\\ \\ \therefore \: V_{pipe} =3.14 {(3)}^{2} (32) \\ \\ \therefore \: V_{pipe} = 904.32 \\ \\ \therefore \: V_{pipe} \approx 904 \: {ft}^{3}](https://tex.z-dn.net/?f=%20%5Ctherefore%20%5C%3A%20V_%7Bpipe%7D%20%3D%5Cpi%20%7Br%7D%5E%7B2%7D%20h%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20V_%7Bpipe%7D%20%3D3.14%20%7B%283%29%7D%5E%7B2%7D%20%2832%29%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20V_%7Bpipe%7D%20%3D3.14%20%7B%283%29%7D%5E%7B2%7D%20%2832%29%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20%20V_%7Bpipe%7D%20%3D%20904.32%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20V_%7Bpipe%7D%20%20%20%5Capprox%20904%20%5C%3A%20%20%7Bft%7D%5E%7B3%7D%20)
Hence, the volume of pipe in nearest whole number is 904 cubic feet.
Answer: 0.76
Step-by-step explanation:
We know that the sample proportion is the best estimate of the population proportion. (1)
Given : Gallup reported that of the 1,005 people surveyed, 76% of U.S. workers believe that they will continue working past retirement age.
Let p be the population proportion.
We have sample proportion: ![\hat{p}=76\%=0.76](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D76%5C%25%3D0.76)
Therefore, the estimated proportion of U.S. workers believe that they will continue working past retirement age from the sample = ![\hat{p}=0.76](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D0.76)
