Question

a cylinder has a radius of 5 and height of 3. what is the volume

Answer 1

Answer: Volume of the cylinder is 75π or 235.62 cm³

                    Volume of cylinder =πr²h

                                        where r is radius and h is height.

Here given radius = 5 and height = 3

Using the formula: πr²h

                              : π * 5² * 3

                              : π * 5 * 5 * 3

                              : 75π or 235.62 cm³

Answer 2

Answer:

The volume of cylinder is 235.5 units³.

Step-by-step explanation:

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

$\longrightarrow{\boldsymbol{V_{(Cylinder)} = \pi{r}^{2}h}}$

• V = Volume
• π = 3.14
• r = radius
• h = height

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

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

$\longrightarrow{\sf{V_{(Cylinder)} = 3.14{(5)}^{2}3}}$

$\longrightarrow{\sf{V_{(Cylinder)} = 3.14(5 \times 5)3}}$

$\longrightarrow{\sf{V_{(Cylinder)} = 3.14(25)3}}$

$\longrightarrow{\sf{V_{(Cylinder)} = 3.14 \times 25 \times 3}}$

$\longrightarrow{\sf{V_{(Cylinder)} = 78.5 \times 3}}$

$\longrightarrow{\sf{V_{(Cylinder)} = 235.5}}$

$\star{\underline{\boxed{\sf{\red{V_{(Cylinder)} = 235.5 \: {units}^{3}}}}}}$

Hence, the volume of cylinder is 235.5 units³.
