Answer 1

V = 60

Explanation:

V = πr²h

=> V = π(2)²(5)

=> V = 20π

=> V = 20(3)

=> V = 60

Answer 2

The answer is
`\bf{V \approx \Big[62.80\Big] \: {in}^(3)}`.

Step-by-step explanation:

`\large\star \: {\tt{\underline{\underline{\red{SOLUTION}}}}}`

As per given data we have :

• 
  `\small\pink\bull` Radius of cylinder = 2 in
• 
  `\small\pink\bull` Height of cylinder = 5 in

We need to find the volume of cylinder.

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

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

• 
  `\blue\star` V = Volume
• 
  `\blue\star` π = 3.14
• 
  `\blue\star` r = radius
• 
  `\blue\star` h = height

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

`\longrightarrow{\sf{Volume_((Cylinder)) = \pi{r}^(2)h}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = 3.14{(2)}^(2)5}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = (314)/(100) {(2 * 2)}5}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = (314)/(100) {(4)}5}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = (314)/(100) * 4 * 5}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = (314)/(100) * 20}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = (314 * 20)/(100)}}`

`\longrightarrow{\sf{Volume_((Cylinder)) = (6280)/(100)}}`

`\longrightarrow{\sf{Volume_((Cylinder)) \approx 62.80 }}`

`\star\underline{\boxed{\sf{\purple{Volume_((Cylinder)) \approx 62.80 \: {in}^(3)}}}}`

Hence, the volume of cylinder is 62.80 in³.

`\rule{300}{2.5}`
