Thread: % error View Single Post
 P: 9 Hi if i have to find the percentage error of a volume measurement in a cylindrical column , how do i do it please? height x pi x r2 I know that the height has a % error of 4%, the radius is 0.5cm +/- 0.1cm so that would mean in the radius the % error is : 0.1/0.5 x 100 = 20% but what happens to the overall % erro in the volume( considering the radius is squared?) Thanks
