The moon is about 384000 km from earth and its path around the earth is nearly circular. Find the length of path described by moon in one complete revolution. (Take π = 3.14)
Solution:
Given, the moon is about 384000 km from earth and its path around the earth is nearly circular.
We have to find the length of the path described by the moon in one complete revolution.
The length of the path by moon in one complete revolution = circumference
Circumference = 2πr
Given, radius = 384000 km
= 2(3.14)(384000)
= 2(314)(3840)
= 2411520 km
Therefore, the circumference is 2411520 km.
✦ Try This: The moon is about 464000 km from earth and its path around the earth is nearly circular. Find the length of path described by moon in one complete revolution. (Take π = 3.14)
Given, the moon is about 464000 km from earth and its path around the earth is nearly circular.
We have to find the length of the path described by the moon in one complete revolution.
The length of the path by moon in one complete revolution = circumference
Circumference = 2πr
Given, radius = 464000 km
= 2(3.14)(464000)
= 2(314)(4640)
= 2913920 km
Therefore, the circumference is 2913920 km.
