On A Clear Day, You Can See About 27 Miles From The Observation Deck Of The Empire State Building In New York City. Using The Formula Below, Estimate The Height In Feet, $h$, Of The Observation Deck. The Distance, $d$, Is In

Introduction

The Empire State Building is one of the most iconic landmarks in New York City, standing tall at an impressive height of 1,454 feet (443 meters). However, on a clear day, the observation deck offers breathtaking views of the city, stretching out to about 27 miles (43.4 kilometers) in every direction. In this article, we will use a simple trigonometric formula to estimate the height of the observation deck, given the distance to the horizon.

The Formula

The formula we will use is based on the concept of the horizon, which is the apparent line where the Earth's surface meets the sky. The distance to the horizon can be calculated using the following formula:

$$d = \sqrt{2 \times h \times H}$$

where:

• $d$ is the distance to the horizon in miles
• $h$ is the height of the observer above sea level in feet
• $H$ is the radius of the Earth in miles

The Radius of the Earth

The radius of the Earth is approximately 3,959 miles (6,371 kilometers). We will use this value in our calculation.

The Height of the Observation Deck

We are given that the distance to the horizon is 27 miles. We can plug this value into the formula, along with the radius of the Earth, to solve for the height of the observation deck:

$$27 = \sqrt{2 \times h \times 3959}$$

Solving for h

To solve for $h$, we can square both sides of the equation:

$$27^2 = 2 \times h \times 3959$$

$$729 = 7918 \times h$$

Now, we can divide both sides by 7918 to solve for $h$:

$$h = \frac{729}{7918}$$

Calculating the Height

Using a calculator, we can calculate the value of $h$:

$$h \approx 0.092$$

However, this is not the height of the observation deck above sea level. To find the height of the observation deck, we need to add the height of the Earth's surface to the calculated value of $h$. The height of the Earth's surface is approximately 0.5 miles (0.8 kilometers).

The Final Answer

Adding the height of the Earth's surface to the calculated value of $h$, we get:

$$h \approx 0.092 + 0.5$$

$$h \approx 0.592$$

However, this is still not the height of the observation deck above sea level. To find the height of the observation deck, we need to multiply the calculated value of $h$ by the radius of the Earth:

$$h \approx 0.592 \times 3959$$

$$h \approx 2345.5$$

Conclusion

Using the formula and the given distance to the horizon, we estimated the height of the observation deck to be approximately 2345.5 feet. This is a rough estimate, as the actual height of the observation deck is 1,454 feet. However, this calculation demonstrates the power of simple trigonometry in estimating the height of objects.

Limitations of the Calculation

There are several limitations to this calculation. Firstly, the formula assumes a flat Earth, which is not the case. The Earth is an oblate spheroid, meaning that it is slightly flattened at the poles and bulging at the equator. This means that the distance to the horizon will be slightly different depending on the location and the height of the observer.

Secondly, the calculation assumes that the observer is at sea level. However, the observation deck of the Empire State Building is at an altitude of 850 feet (259 meters) above sea level. This means that the calculated height of the observation deck will be slightly lower than the actual height.

Finally, the calculation assumes that the distance to the horizon is 27 miles. However, this value can vary depending on the location and the height of the observer.

Future Improvements

There are several ways to improve this calculation. Firstly, we can use a more accurate value for the radius of the Earth. The radius of the Earth is approximately 3,959 miles (6,371 kilometers), but this value can vary depending on the location and the method of measurement.

Secondly, we can use a more accurate value for the height of the observation deck. The height of the observation deck is 1,454 feet (443 meters), but this value can vary depending on the location and the method of measurement.

Finally, we can use a more accurate formula to calculate the distance to the horizon. The formula we used is based on the concept of the horizon, but it assumes a flat Earth and does not take into account the curvature of the Earth.

Conclusion

In conclusion, we estimated the height of the observation deck of the Empire State Building using a simple trigonometric formula. The calculated height was approximately 2345.5 feet, which is a rough estimate of the actual height of 1,454 feet. However, this calculation demonstrates the power of simple trigonometry in estimating the height of objects.
