WebThat depends on how you need to express the radius. For example, f (x) = x^2: Rotation around the x-axis will give us a radius equal to the fuction value, Rotation around the y-axis will give us a radius equal to the x-value, so we need an expression for the x-value. Thats why we do the inverse of the function. WebSince the volume of a solid cylinder is ˇ(radius)2 height, the volume of the cylindrical shell is V = ˇr2 2 h ˇr 2 1 h = ˇ(r2 2 r 2 1)h = ˇ(r 2 + r 1)(r 2 r 1)h = 2ˇ r 2 + r 1 2 h(r 2 r 1) Let r = r 2 r 1, the thickness of the cylindrical shell, and let r = (r 2 + r 1)=2, the average of the outer and inner radii of the cylindrical shell. christmas hidden pictures online
