find the volume of the cylinder below use the approximation 3.14 for pi. radius 5 cm 15 cm

1 answer

To find the volume of a cylinder, you can use the formula:

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

where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.

Given:

  • Radius \( r = 5 \) cm
  • Height \( h = 15 \) cm
  • Use \( \pi \approx 3.14 \)

Now, let's plug in the values:

\[ V = 3.14 \times (5)^2 \times 15 \]

Calculating \( (5)^2 \):

\[ (5)^2 = 25 \]

Now, substitute back into the volume formula:

\[ V = 3.14 \times 25 \times 15 \]

Now calculate \( 25 \times 15 \):

\[ 25 \times 15 = 375 \]

Now substitute that result into the equation:

\[ V = 3.14 \times 375 \]

Now we perform the final multiplication:

\[ V = 1177.5 \]

Thus, the volume of the cylinder is approximately \( 1177.5 \) cubic centimeters.
