Volume of a cylinder=pi*radius^2*height If diameter=4+2x, then radius=2+x radius^2=x^2+4x+4 Volume=pi(5x^3+10x^2+20x+x^2+4x+4) Volume=pi(5x^3+11x^2+24x+4) Depending on what your x value is, plug it in to get an answer

Just a fun fact: the first equation is a circle with radius of 5 (square root of 25). I'll use substitution to answer this. Let's start with defining x: x=10-2*y Insert into the first equation: (10-2*y)^2+y^2=25 Expand the equation: 100-20y-20y+4y^2+y^2=25 Simplify: 5y...
