Answer:
x = 4
Step-by-step explanation:
3x + x + (x + 3) = 23 feet
3x + x + x = 20 feet
5x = 20 feet
x = 20/5
x = 4
Answer:
tell me if im wrong but. 45?
Step-by-step explanation:
Answer:
2:34
Step-by-step explanation:
24 hours time format will only change 1 pm-12 am, those will change to 13-24 so 2:34 am is just 2:34
Answer: Ratio of new volume to original volume is 2:1.
Step-by-step explanation:
Let the radius of cylinder be 'r'
Let the height of cylinder be 'h'
Original volume of cylinder will be
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
If radius get doubled,
New radius be '2r'
If height get halved,
New height be will be
![\frac{h}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B2%7D)
so, Volume of cylinder becomes
![Volume=\pi (2r)^2\times \frac{h}{2}=\pi \times 4r^2\times \frac{h}{2}\\\\Volume=2\pi r^2h](https://tex.z-dn.net/?f=Volume%3D%5Cpi%20%282r%29%5E2%5Ctimes%20%5Cfrac%7Bh%7D%7B2%7D%3D%5Cpi%20%5Ctimes%204r%5E2%5Ctimes%20%5Cfrac%7Bh%7D%7B2%7D%5C%5C%5C%5CVolume%3D2%5Cpi%20r%5E2h)
Ratio of new volume to the original volume is given by
![2\pi r^2h:\pi r^2h\\\\2:1](https://tex.z-dn.net/?f=2%5Cpi%20r%5E2h%3A%5Cpi%20r%5E2h%5C%5C%5C%5C2%3A1)
Hence, Ratio of new volume to original volume is 2:1.
