Diameter of the jar is 20cm
First of all, let us calculate the volume in cm³.
As, 1L = 1000cm³
So, 11 L vessel has volume 11000cm³.
Again, we know,the formula of volume of a cylinder is given as Пr²h
So, Пr²h = 11000
where, h is the height of the cylinder = 35cm.
So, (22/7)*r²*35 = 11000 [Taking П = 22/7]
So, 110r² = 11000
r² = 11000/110 = 100
So, r = sqrt(100) = 10 [Length cant be negative so -10 ignored]
Diameter = 2r = 20cm
