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
Answer:
cost price = 5000 rs.
selling price = 6500 rs.
as selling price > cost price there is a profit
profit = selling price - cost price = 6500 - 5000 = 1500 rs.
profit percentage = profit x 100 / cost price = 1500 x 100 / 5000 = 30 %
