% error

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
