Question

a rectangle with a length of 18 in and width of 10in is rotated around the width side what is the volume

Answer 1

6. We will have that if we rotated the rectangle and then determined the cross-section shape, the volume would be given by the following expression:

$V=l\cdot w\cdot l\Rightarrow A=l^2\cdot w$

Now, we replace the values:

$V=(18)^2\cdot(10)\Rightarrow V=3240$

So, the volume of the shape delimited by the cross-section would be 3240 cubic inches.
