Answer: The error of the diameter would be 5% .
Step-by-step explanation:
Since we have given that
Here, r is the radius
h is the height
So, it becomes,
So, we will derivate S wrt D, we get that
---------------------(1)
As we have given that
it will take to paint the side of the tank to within 5% of the true amount.
So, it becomes,
---------------(2)
So, from (1) and (2) , we get that
Hence, the error of the diameter would be 5% .
Answer:
Step-by-step explanation:
First, use PEMDAS to distribute the -2 to the parenthesis.
Combine like terms on the right side.
Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.
Now subtract the 2f from both sides.
Divide both sides by 10.
Simplify.
