It is a well known fact that during a total solar eclipes the disc of the moon almost completely covers the disc of the sun. From this fact and from the information you can gather from Solved Examples 3 and 4 on page 1//44, determine the approximate diameter of the moon.

Explanation

To determine the approximate diameter of the Moon using the information about a total solar eclipse, we can use the concept of similar triangles. Here’s a step-by-step solution:

### Step 1: Understand the Geometry of the Situation
During a total solar eclipse, the Moon completely covers the Sun from the perspective of an observer on Earth. We can visualize this scenario as two similar triangles: one triangle formed by the Sun and the distance to the Earth, and the other triangle formed by the Moon and its distance to the Earth.

### Step 2: Define the Distances
- Let the distance from the Earth to the Moon be denoted as \( ME \) (approximately \( 3.84 \times 10^8 \) meters).
- Let the distance from the Earth to the Sun be denoted as \( SE \) (approximately \( 1.496 \times 10^{11} \) meters).
