find the volume of cylinder radius is 3cm height is 6cm

1 answer

To find the volume \( V \) of a cylinder, you can use the formula:

\[ V = \pi r^2 h \]

where:

  • \( r \) is the radius of the cylinder
  • \( h \) is the height of the cylinder
  • \( \pi \) is a mathematical constant approximately equal to 3.14159

Given:

  • Radius \( r = 3 \) cm
  • Height \( h = 6 \) cm

Plugging in the values:

\[ V = \pi (3 , \text{cm})^2 (6 , \text{cm}) \]

\[ V = \pi (9 , \text{cm}^2) (6 , \text{cm}) \]

\[ V = \pi \times 54 , \text{cm}^3 \]

Now, approximating \( \pi \) as 3.14:

\[ V \approx 3.14 \times 54 , \text{cm}^3 \]

\[ V \approx 169.56 , \text{cm}^3 \]

Thus, the volume of the cylinder is approximately \( 169.56 , \text{cm}^3 \).
