To calculate: The length of tunnel that could be dug to the center of the Earth whose circumference of equator is about
Answer to Problem 16E
The length of tunnel that could be dug from the surface of Earth’s equator to the center of it is
Explanation of Solution
Given information:
The circumference of Earth’s equator is approximately
Formula used:
Circumference
A straight line from surface to center of circle represents the radius of the circle.
Calculation:
Consider the given statement that the circumference of Earth’s equator is approximately
Recall that a straight line from surface to center of circle represents the radius of the circle.
So, the length of tunnel that could be dug from the surface of Earth’s equator to the center will represent the radius of it.
Recall that the circumference
Apply it,
Rounding off to the nearest tenth, we get,
Thus, the length of tunnel that could be dug from the surface of Earth’s equator to the center of it is
