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.

Given:

  • Diameter = 42 m, so the radius \( r = \frac{42}{2} = 21 \) m,
  • Height \( h = 16 \) m,
  • Using \( \pi = 3.14 \).

Now substitute these values into the formula:

\[ V = 3.14 \times (21)^2 \times 16 \]

First, calculate the area of the base:

\[ (21)^2 = 441 , \text{m}^2 \]

Now substitute this into the volume formula:

\[ V = 3.14 \times 441 \times 16 \]

Calculate \( 441 \times 16 \):

\[ 441 \times 16 = 7056 \]

Now multiply by \( 3.14 \):

\[ V = 3.14 \times 7056 \approx 22,155.84 , \text{m}^3 \]

So, the solution for the volume of the cylinder is:

22,155.84 m³
