Hi there, I am here cause one of my collegues asked me a question that I didnt know (didnt tell het that). She titled her e-mail as "I hate Maths" hence why. Perhaps you could help.

A hemispherical dome of radius r metres has a volume of V given by V=2/3 pie r cubed

If the error in measuring V is dV and the corresponding error in calculating r is dr, obtain a formula giving a good approximation for dr I'm terms of V and dV.

Calculate the value of r and the maximum error in dr when the volume 525 m cubed with a maximum error of 0.5m cubed. To 4 Sig fig - May 1st 2012, 02:35 AMemakarovRe: I hate Math
We have , so dr can be expressed through dV and r. Further, r can be expressed through V. If I am not mistaken, .

That title made my day.
