QUESTION: 1

### A circle of radius 7 m has a standard error of 0.02 m on the radius. The standard error of its area is

Solution:

Area of circle
A = πr2
∴ dA/dr = 2πr
Let standard error in radius be er,
∴ Standard error in area,

QUESTION: 2

Solution:
QUESTION: 3

### The difference between the most probable value of a quantity and its observer value is

Solution:

True Error = Actual Value-Observed Value
Weighted Observations = Observations taken with proportion to any quantity like an area
Conditional Error = Error occurring due to certain conditions prevailing. Like temperature error.
Residual Error = Most Probable Value- Observed Value

QUESTION: 4

The error due to bad ranging is

Solution:

Cumulative Errors occurring in same direction and thus, they aggregate to make a considerable amount of error.
Positive cumulative errors Non Horizontality, sag, bad ranging.
Positive/ Negative cumulative errors Erroneous length of chain, temperature variation.

QUESTION: 5
