Answer 1

The volume of cylinder is 648 cm³.

Explanation:

Here's the required formula to find the volume of cylinder :

`\longrightarrow{\pmb{\sf{V = \pi{r}^(2) h}}}`

• 
  `\pink\star` V = Volume
• 
  `\pink\star` π = 3
• 
  `\pink\star` r = radius
• 
  `\pink\star` h = height

Substituting all the given values in the formula to find the volume of cylinder :

`\begin{gathered} \qquad{\longrightarrow{\sf{V = \pi{r}^(2)h}}}\\\\\qquad{\longrightarrow{\sf{V = 3{(6)}^(2)6}}}\\\\\qquad{\longrightarrow{\sf{V = 3{(6 * 6)}6}}}\\\\\qquad{\longrightarrow{\sf{V = 3{(36)}6}}}\\\\\qquad{\longrightarrow{\sf{V = 3* 36 * 6}}}\\\\ \qquad{\longrightarrow{\sf{V = 108 * 6}}}\\\\ \qquad{\longrightarrow{\sf{\red{\underline{\underline{V \approx 648 \: {cm}^(3)}}}}}} \end{gathered}`

Hence, the volume of cylinder is 648 cm³.

Answer 2

`\qquad \quad \large {\pmb{ \frak { \mid {\overline{ \underline{\purple{ \bigstar \: Required \: Answer \: \bigstar}}}}}} \mid}\\`

According to the attachment, we are given –

• π = 3
• Height of cylinder, h = 6cm
• Radius of cylinder, r = 6cm

`\qquad`
`\purple{{\twoheadrightarrow {\pmb{\sf{Volume_((Cylinder)) = \pi{r}^(2)h}}}}}`

`\qquad`
`\twoheadrightarrow\sf Volume_((Cylinder)) = 3 * {6}^2* 6`

`\qquad`
`\twoheadrightarrow\sf Volume_((Cylinder)) = 3 * 36* 6`

`\qquad`
`\twoheadrightarrow\sf Volume_((Cylinder)) =18* 36`

`\qquad`
`\twoheadrightarrow\sf Volume_((Cylinder)) =648 \: cm^3\\\\`

`\therefore{\underline{\textsf{ Volume of cylinder is \textbf{648 cm³}}}}`
