The function is the line that goes through (0, 0) and ( h, r ). Its slope is thus. Now express the volume of a representative disk. The radius of your representative disk is f ( x) and its thickness is dx. Thus, its volume is given by.

WebWashers: Disks with Holes What if we want the volume between two functions? Example: Volume between the functions y=x and y=x3 from x=0 to 1 These are the functions: … WebSep 21, 2024 · Step 3. Find the equation of the areas that are being stacked. We’ve pre-decided that we are going to use the disk (washer) method. There are definitely washers happening, because there is a big outer circle minus a hole (to create the cinder cone). So, we need to stack outer pancakes minus inner pancakes (big circles minus small circles): WebDisc method: revolving around x- or y-axis AP.CALC: CHA‑5 (EU), CHA‑5.C (LO), CHA‑5.C.1 (EK) Google Classroom You might need: Calculator Let R R be the region in the first quadrant enclosed by the x x -axis, the y y -axis, the line y=2 y = 2, and the curve y=\sqrt {9-x^2} y = 9− x2.
