Mark the correct alternative in the following:
The height of a cylinder is equal to the radius. If an error of α% is made in the height, then percentage error in its volume is:
let height of a cylinder=h=radius of that cylinder=r
% error in height Δh/h×100 = a (given)
Volume of cylinder= v =(1/3)×πr2h
We have given that h=r
Then
So,
Finally
=3×a
=3a%
