Using calipers, you find that a nickel cylinder has length 8.625 cm and diameter 1.218 cm. An electronic pan balance shows that its mass is 89.52g .
Find the cylinder's density.
Express your answer to four significant figures and include the appropriate units.

i.e. i have try 27.99/pi g/cm^3 but it is wrong

Hmm, I plugged in 0.609 as r and got 8.908 g/cm³

Oh wow thats the answer thank u
whats the different b/t urs and mine?

ddcamp · Answer

idk.
Maybe you typed it into the calculator wrong?
I did 1.218 / 2 to find the radius, then (pi)r²h for volume.

oh ok...
Anyway, Thanks
