Suppose a function x = f (y), which is rotated about the y-axis. The volume of the solid formed by revolving the region bounded by the curve x = f (y) and the y-axis between y = c and y = d about
Correct answer: Explanation: From calculus, we know the volume of an irregular solid can be determined by evaluating the following integral: Where A (x) is an equation for the cross
The volume of a solid revolution by disk method is calculated as: V = ∫ − 2 3 π ( x 2) 2 d x V = π ∫ − 2 3 x 4 d x V = π [ 1 5 x 5] − 2 3 V = π [ 243 5 − ( − 32 5)] V = 55 π You can also
To solve a math equation, you need to find the value of the variable that makes the equation true.
