Question

Step by step explanation please. i want to try to understand it.

Answer 1

Explanation:

For a single cylinder:

radius (r) = 3 in (Given)

height (h) = 8 in (Given)

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

Explanation:

Answer 2

`V_(composite\: figure) =678.24\: in^3`

Explanation:

• For a single cylinder:

• radius (r) = 3 in (Given)

• height (h) = 8 in (Given)

• It is given that: all the three cylinders are identical, means their radii and heights are equal.

• Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

• 
  `\implies V_(composite\: figure) =3(\pi r^2 h)`

• 
  `\implies V_(composite\: figure) =3(3.14* (3)^2 * 8)`

• 
  `\implies V_(composite\: figure) =3(226.08)`

• 
  `\implies V_(composite\: figure) =678.24\: in^3`
