1. **State the problem:** We need to find the volume of a cone with height $h=14$ meters and base radius $r=6$ meters. 2. **Formula for the volume of a cone:** $$V = \frac{1}{3} \pi r^2 h$$ This formula calculates the volume by taking one-third of the base area times the height. 3. **Substitute the given values:** $$V = \frac{1}{3} \pi (6)^2 (14)$$ 4. **Calculate the square of the radius:** $$6^2 = 36$$ 5. **Plug in and simplify:** $$V = \frac{1}{3} \pi \times 36 \times 14$$ 6. **Multiply 36 and 14:** $$36 \times 14 = 504$$ 7. **So volume is:** $$V = \frac{1}{3} \pi \times 504$$ 8. **Simplify the fraction:** $$V = \pi \times \cancel{\frac{1}{3}} \times \cancel{504} = \pi \times 168$$ 9. **Calculate the numerical value using $\pi \approx 3.1416$:** $$V \approx 3.1416 \times 168 = 527.7872$$ 10. **Round to the tenths place:** $$V \approx 527.8$$ cubic meters. **Final answer:** The volume of the cone is approximately $527.8$ cubic meters.
