Answer: V = 193.25π
Explanation: The method to calculate volume of a solid of revolution is given by an integral of the form:
V =
![\pi\int\limits^a_b {[f(x)]^(2)} \, dx](https://img.qammunity.org/2021/formulas/mathematics/college/muar9n4nt1a5ulin90ikrkumj1oy37mchx.png)
f(x) is the area is the function that rotated forms the solid.
For f(x)=y=
and solid delimited by x = 2 and x = 4:
V =

V =

V =

V =

V = 193.25π
The volume of a solid formed by y =
and delimited by x = 2 and x = 4
is 193.25π cubic units.
