Answer:

V = 60

Explanation:

V = πr²h

=> V = π(2)²(5)

=> V = 20π

=> V = 20(3)

=> V = 60

Answer:

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.
