Answer:
C
Step-by-step explanation:
The median is the middle number
There are 10 data points
The middle is between points 5 and 6
(30+34)/2 = 32
The line in the middle of the box is the median
Choice C is the only option with the line at 32
Step-by-step explanation:
If r and h are the radius and height of the cylinder, then its surface area A is given by :
....(1)
We need to find the cylinder's height in terms of its radius and surface area. Subtracting
on both sides, we get :
![A-2\pi r^2=2\pi rh+2\pi r^2-2\pi r^2\\\\A-2\pi r^2=2\pi rh](https://tex.z-dn.net/?f=A-2%5Cpi%20r%5E2%3D2%5Cpi%20rh%2B2%5Cpi%20r%5E2-2%5Cpi%20r%5E2%5C%5C%5C%5CA-2%5Cpi%20r%5E2%3D2%5Cpi%20rh)
Dividing both sides by
. So,
![\dfrac{A-2\pi r^2}{2\pi r}=\dfrac{2\pi rh}{2\pi r}\\\\h=\dfrac{A-2\pi r^2}{2\pi r}](https://tex.z-dn.net/?f=%5Cdfrac%7BA-2%5Cpi%20r%5E2%7D%7B2%5Cpi%20r%7D%3D%5Cdfrac%7B2%5Cpi%20rh%7D%7B2%5Cpi%20r%7D%5C%5C%5C%5Ch%3D%5Cdfrac%7BA-2%5Cpi%20r%5E2%7D%7B2%5Cpi%20r%7D)
Hence, this is the required solution.
