Question

Ram has a belt large enough to exactly wrap around the Earth along it's circumference.
Hari's belt is 6 feet longer and kept a little higher than Ram's, forming 2 concetric circles around the centre of the Earth.
Find the distance between 2 belts. (i.e. difference between their radii)

Answer 1

Answer:

0.95 feet

Step-by-step explanation:

Let the radius of earth be R

Hence length of rams belt is 2(pi)R and length of Haris belt is 2(pi)R+6

Let this make a circle of radius R'

Therefore

2(pi)R'=2(pi)R+6

2(pi)(R'-R)=6

R'-R=3/3.14=0.95

Hope this answer helped you
