Finding the Volume of a Solid In Exercises 13-22, use the shell method to write and evaluate the definite integral that represents the volume of the solid generated by revolving the plane region about the x-axis.

To determine

**To calculate:** The value of definite integral that represents the volume of the solid generated by revolving the plane region by *x*-axis.

**Given:**

The provided information is

**Formula Used:**

Volume of the plane rotated about *y*-axis is calculated using the formula,

Volume =

**Calculation:**

The graph is:

Since the plane is rotated about *x*-axis, use a horizontal representative rectangle to find the integral. The width of the rectangle *y* is the variable of integration.

The distance from axis of revolution to the center of the rectangle is,

The height of the rectangle is,
