Answer:
r = 5.848cm, h = 11.696cm
Step-by-step explanation:
Surface area:
Volume:
Therefore, the height of a cylinder given its volume would be , thus:
We now find the derivative of the surface area of the cylinder with respect to its radius and set it equal to 0, solving for the radius:
If , then the surface area of the cylinder increases
Therefore, the surface area is minimized when the radius is , making the minimum height .
In conclusion, the 2nd option is correct.
The Answer: is ( Right . )
For the second answer is ( reflected over the x axis . )
The third one is stretch by a factor of 3 .
the fourth one is graph A
Step-by-step explanation:
The answer is 2
Step-by-step explanation: 100% is the highest score you can have . then you have to divide 25 by 100 because 25 is the total amount of questions ,you should get 4,wich means each question is worth 4 points.
