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

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

where:

  • \( V \) is the volume,
  • \( r \) is the radius,
  • \( h \) is the height, and
  • \( \pi \) is approximately 3.14.

Given:

  • \( r = 12 \) cm
  • \( h = 32 \) cm

Now, substitute the values into the formula:

\[ V = 3.14 \times (12)^2 \times 32 \]

First, calculate \( (12)^2 \):

\[ (12)^2 = 144 \]

Now, substitute \( 144 \) back into the equation for volume:

\[ V = 3.14 \times 144 \times 32 \]

Now, calculate \( 144 \times 32 \):

\[ 144 \times 32 = 4608 \]

Now, multiply by \( 3.14 \):

\[ V = 3.14 \times 4608 \]

Calculating this gives:

\[ V = 14461.92 \]

Thus, the volume of the cylinder is:

\[ \boxed{14461.92} , \text{cm}^3 \]
