You measure the mass of an unknown object and obtain measurements of 25.6 g and 25.3 g. What is the percentage difference between the two measurements?

The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm.

(a) Use differentials to estimate the maximum error in the calculated area of the disk.

(b) What is the relative error? What is the percentage error?

For this lab we had to measure the mass, length, width and heightof a Al retangle.
We also had to measure the mass, length and widthof a sheet of Alfoil. The measurements of the rectangle are; mass: 33.26g, Length:7.60cm, Width:2.46cm, Height:.60cm. The measurements of the foilare: Mass:0.76cm, Length:11.90cm, Width:10.99cm. Our teacher wantsus to find the volume of the Al foil by using this equation: AlRectangle Al foil
Mass mass
_______ = ______
volume Volume

With the measurements pluged in the equation looks like this:
Al Rectangle Al foil
33.26g 0.76g
_____ = _____
11.217 volume
I'm lost please help me.
