WebApr 13, 2024 · The Disc Method involves slicing the solid into cylindrical shells, while the Washer Method involves slicing the solid into washers. Q: When should I use the Disc Method? A: The Disc Method is typically used when the axis of revolution is the x-axis, and the function to be rotated is bounded by y = c and y = d. Q: When should I use the … WebVolumes by Cylindrical Shells: the Shell Method Another method of find the volumes of solids of revolution is the shell method. It can usually find volumes that are otherwise …
WebThe only difference with the disk method is that we know the formula for the cross-sectional area ahead of time; it is the area of a circle. This gives the following rule. The Disk Method Let f (x) f ( x) be continuous and nonnegative. WebSep 21, 2024 · Method 1: Disk (washer) Method. Remember, the disk and washer method are the same thing. In the disk method, we visualize stacked circles (or pancakes, as I like to say). The washer method is the same stacked pancakes with holes (like washers or donuts). I like to complete every problem with the same thought process.
WebThe Shell Method vs the Disk Method. The shell method, also known as the method of cylindrical shells, is another method used to calculate the volume of a solid of … Webe. Shell integration (the shell method in integral calculus) is a method for calculating the volume of a solid of revolution, when integrating along an axis perpendicular to the axis of revolution. This is in contrast to disc …
WebApr 13, 2024 · The formula to calculate the volume of the solid using the washer method is given as: V = π∫_a^b (R²-r²) dx. where R is the external radius, r is the internal radius, and dx is the thickness of the washers. “a” and “b” represent the limits of integration. To calculate the external radius, R, we need to first find the distance of ...

Anyhow, your intuition is more or less correct. The shell method asks for height of "cylinders" parallel to your axis of revolution: you're usually given the function in terms of y, so if you're revolving around y, that's easy. clayton widmer
