Given information:-
r = 824.7*10^6 km , Θ = 35.72" arc
To find
l = ?
Solution
First convert Θ value in kilometres.
Note:- here, we divided by 3600 that is to convert in kilometres and then π\180 to convert in radian.
Now, Θ = l / r , r*Θ = l
So, when we convert in scientific notation then,
Therefore , Diameter of Jupiter = 1.42*10^5km
