Answer:
The radius of the can is 7.28 cm .
Step-by-step explanation:
By our general knowledge, a "can" is a cylinder. It is given that the volume of can is 2500 cm³ and the height is 15 cm tall so we have to use the formula of volume of cylinder to find the radius :
![v = \pi {r}^{2} h](https://tex.z-dn.net/?f=v%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20h)
Let r be radius, v be volume and h be height,
Let v = 2500 cm³,
Let h = 15 cm,
![2500 = \pi \times {r}^{2} \times 15](https://tex.z-dn.net/?f=2500%20%3D%20%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%2015)
![\pi \times {r}^{2} = 2500 \div 15](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%3D%202500%20%5Cdiv%2015)
![\pi \times {r}^{2} = \frac{500}{3}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B500%7D%7B3%7D%20)
![{r}^{2} = \frac{500}{3\pi}](https://tex.z-dn.net/?f=%20%7Br%7D%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B500%7D%7B3%5Cpi%7D%20)
![r = \sqrt{ \frac{500}{3\pi} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%7B%20%5Cfrac%7B500%7D%7B3%5Cpi%7D%20%7D%20)

Answer:
![\frac{18}{55}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B55%7D)
Step-by-step explanation:
Which fraction is bigger?
or ![\frac{18}{55}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B55%7D)
If you look closely the fraction
, it looks big but it actually isn't.
The fraction that is bigger is
. This is because 75 is a big number and its only 27 out of the 75. In
, it's not as big as 75. So compare 18 and 27 and 75 and 55. 75 is 20 more than 55. The number 27 is only 9 bigger than 18.
That's why your answer is
![\frac{18}{55}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B55%7D)
Hope this helps!

Answer:
13,250,000 feet or 13.25 million feet
Step-by-step explanation:
Each person in the line has a shoulder width of 1.325 feet.
For each person, there is a width of 1.325 ft. There are 10 million people.
Since:
10 million = 10,000,000
The total length must be:
![1.325 * 10,000,000](https://tex.z-dn.net/?f=1.325%20%2A%2010%2C000%2C000)
![1.325 * 10,000,000 = 13,250,000](https://tex.z-dn.net/?f=1.325%20%2A%2010%2C000%2C000%20%3D%2013%2C250%2C000)
Answer: 13,250,000 feet or 13.25 million feet
