use the metric prefixes table to answer the following questions. 4. the radius of the earth is 6378 km. what is the diameter of the earth in meters? in an experiment, you find the mass of a cart to be 250. metric prefixes: giga = 1000000000 billion; mega = 1000000 million; kilo = 1000 thousand; centi = 1/100 hundredth; milli = 1/1000 thousandth; micro = 1/1000000 millionth; nano = 1/1000000000 billionth

use the metric prefixes table to answer the following questions. 4. the radius of the earth is 6378 km. what is the diameter of the earth in meters? in an experiment, you find the mass of a cart to be 250. metric prefixes: giga = 1000000000 billion; mega = 1000000 million; kilo = 1000 thousand; centi = 1/100 hundredth; milli = 1/1000 thousandth; micro = 1/1000000 millionth; nano = 1/1000000000 billionth

Answer

Explanation:

Step1: Find the diameter in kilometers

The diameter $d$ of a circle is related to the radius $r$ by the formula $d = 2r$. Given $r=6378$ km, so $d = 2\times6378$ km$=12756$ km.

Step2: Convert kilometers to meters

Since 1 km = 1000 m, to convert 12756 km to m, we multiply by 1000. So $12756\times1000$ m$ = 12756000$ m.

Answer:

12756000 m
