Question

the moon is about 38400 km from the earth and its path around the earth is nearly circular find the circumference of the path described by the moon in one complet revolution about the earth

Answer 1

distance from earth to moon=38400 km. (given)
radius =38400km
circumference =2πr
2*38400*22/7=241371.429km

Answer 2

Answer:

2411520 km

Step-by-Step Explanation:

Given:-

Radius(r)= 384000 km

Circumference = ????

Solution:

The length of the path described by the moon in 1 complete revolution  

= 2πr

= 2 * 3.14 * 384000

= 6.28 * 384000 km

= 2411520 km  

∴ The length of the path described by the moon in 1 complete revolution  is 2411520 km .
