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)

Advertisements

Solution

Length of path described by moon in one complete revolution = 2πr

= 2 × 3.14 × 384000  ......[∵ Radius = Distance of moon from the earth]

= 2411520 km
