Answer:
radius r = 3.414 in
height h = 6.8275 in
Step-by-step explanation:
From the information given:
The volume V of a closed cylindrical container with its surface area can be expressed as follows:


Given that Volume V = 250 in²
Then;

We also know that the cylinder contains top and bottom circle and the area is equal to πr²,
Hence, if we incorporate these areas in the total area of the cylinder.
Then;



To find the minimum by determining the radius at which the surface by using the first-order derivative.




![r =\sqrt[3]{39.789}](https://tex.z-dn.net/?f=r%20%3D%5Csqrt%5B3%5D%7B39.789%7D)
r = 3.414 in
Using the second-order derivative of S to determine the area is maximum or minimum at the radius, we have:


Thus, the minimum surface area will be used because the second-derivative shows that the area function is higher than zero.
Thus, from 

h = 6.8275 in
Im hoping you just want an example so here you go
whole number: 16
fraction version of 16: 16/1
to subtract fractions you have to have a common denominator.
so if i had a problem like 6 -1/3
step 1 would be to turn 6 into a fraction: 6/1
step 2 is to find the common denominator:
6/1 -1/3, in this case it is 3, so you multuply the first term by 3
you would then get 18/3 - 1/3, now all you do if subract numerators, 18-3=15
final answer would be 15/3, you can simplify it into 5/1 which is also 5
Answer:
9/4
Step-by-step explanation:
1 2/7=9/7
2 1/3=7/3
--------------
9/7+7/3x+3/14+x=9
18/14+3/14+7/3x+3/3x=9
21/14+10/3x=9
10/3x=9-21/14
10/3x=9-3/2
10/3x=18/2-3/2
10/3x=15/2
x=(15/2)/(10/3)
x=(15/2)(3/10)
x=45/20
simplify
x=9/4
