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. WebIn the disk method we use the radius from the origin, but to calculate the surface area of a sphere you use the integral of the difference between the inner radius and the outer radius (like one of those rings of Saturn). If you use the disk approach with a ring that has a thickness of 0, you will notice that the method checks out! shoes of the 50s https://thecircuit-collective.com
