8 ... u gotta add 5+3 which is 8 soo ya\ prolly wrong (I kinda stink at math)but whatevs
V= 3.14r^2h
10/2= r
5^2= 25
(3.14)(25)(6)
V=471
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
The answer to your question is C
