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
radius, r = 9 inches
error = 0.5 inch
The area of the end is
A = 3.14 x r x r = 3.14 x 9 x 9 = 254.34 in^2
So, the area is given by
220.00
-185.00
= 35.00 the difference of what was paid at the same prices.
(x+10)²=x²+20x+100
