To find the volume \( V \) of a right circular 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 approximately 3.14.
Given:
- Diameter = 42 m, so Radius \( r = \frac{42}{2} = 21 \) m,
- Height \( h = 16 \) m.
Now substituting the values into the formula:
\[ V = 3.14 \times (21)^2 \times 16 \]
First, calculate \( (21)^2 \):
\[ 21^2 = 441 \]
Now substitute this back into the volume formula:
\[ V = 3.14 \times 441 \times 16 \]
Now calculate \( 441 \times 16 \):
\[ 441 \times 16 = 7056 \]
Now substitute this product back into the volume formula:
\[ V = 3.14 \times 7056 \]
Now calculate the final volume:
\[ V = 22173.84 \text{ m}^3 \]
Rounding to two decimal places or choosing from the given responses, the closest value is:
22,155.84 m³
Thus, the answer is: 22,155.84 m³.
