the moon is about 3,84,000km away from the earth and its path around the earth is nearly circular. find the circumference of the path described by the moon in one complete revolution about the earth. (piee r=3.14)
Answers
Radius of circular path = moon distance + earth radius = 384000+6371 = 390371 km
Circumference of circular path =2 pi r = 2×3.14×390371= 2451529.88 km
Approximately 2451530 km
Step-by-step explanation:
Solution :
Moon Revolves round the earth .
The distance travelled is simply the circumference of circle .
we know that ,
Circumference Of Circle = 2*π*r (where r is radius of Circle)
Here Distance Between earth and moon = Radius of Circle = 385000kms
therefore distance traveled by moon in a month = 2*π*r
=2*22/7*385000 kms
=2*22*55000kms
=44*55000 kms
=2.4×10^6 km
