Answer:

$HJ=42\ m$

Step-by-step explanation:

we know that

In a parallelogram opposite sides are equal and parallel

The figure FHJM is a parallelogram

The measurement of the radius of the end of a log is found to be 9 inches, with a possible error of 1/2 inch. Use differentials

enot [183]

Answer:

$\pm 9in^2$

Step-by-step explanation:

We are given that

Radius of end of a log, r= 9 in

Error, $\Delta r=\pm 1/2$ 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= $pi r^2$

$\frac{dA}{dr}=2\pi r$

$\frac{dA}{dr}=2\pi (9)=18\pi in^2$

Now,

Approximate error in area

$dA=\frac{dA}{dr}(\Delta r)$

Using the values

$dA=18\pi (\pm 1/2)$

$\Delta A\approx dA=\pm 9in^2$

Hence, the possible propagated error in computing the area of the end of the log $=\pm 9in^2$
