A cylinder of length 5 and diameter 2 units is constructed such that the density of the material comprising it varies as the distance from the base. If K is a proportionality constant such that the density is given by K * distance from base, use an integral to show that the
mass of the cylinder is given by : M =25Kpi/2
Area of Circle : A = pi* r^2
The Attempt at a Solution
Fairly stuck with this question. I am not even sure where to begin with this. I am certain it isn't a very difficult problem but I am just not sure where to begin with it. Its going to consist of a definite integral somewhere along the line.
I understand that questions don't get answered without some sort of an attempt but I am stumped at where to begin with this.
