You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.
8 = 4 * 2
You can take the square root of 4 and put it outside the root.
18 = 9 * 2
You can take the square root of 9 and put it outside the root.

Answer:
Revolutions=37079108.61 rev
Step-by-step explanation:
First if all we have to make the units same to calculate the revolutions
Since distance gis gien in km and radius is given in m we will covert distance to m first.
Distance =S=65000km
Distance=S=65000km*1000m/km
Distance = S= 65000000m
Formula:
S=rθ
where
S is the distance
r is the radius
θ is the revolution in radian
θ=S/r
θ=65000000/0.279
θ=232974910.4 rad
Revolutions=θ/2π
Revolutions=232974910.4/2π
Revolutions=37079108.61 rev
