1. The problem statement, all variables and given/known data 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 2. Relevant equations Area of Circle : A = pi* r^2 3. The attempt at a solution Fairly stuck with this question. Im not even sure where to begin with this. Im certain it isnt a very difficult problem but Im 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 im stumped at where to begin with this.
