(9-(6-3))x2 hopefully this helps you out!!!
Answer:

Step-by-step explanation:
We are given that
Radius of end of a log, r= 9 in
Error,
in
We have to find the error in computing the area of the end of the log by using differential.
Area of end of the log, A=


Now,
Approximate error in area

Using the values


Hence, the possible propagated error in computing the area of the end of the log
The measure of y would be 110° i believe
Your answer is gonna be C
