Calculate the time it takes a plane traveling at a constant tangential speed of 110 m/s., to fly once around a circle whose radius is 2850m.


The formula for tangential speed is
v = r.w or v = r.2.Pi/T so
110 = 2850.2.Pi/T
T = 162.8

is this a question?
 
Yes this is a question with an answering to it.
I want to know is it ture?
 
looks good to me

what your doing in the equations is effectively fiinding the circumference C = 2.pi.r the diving this by the speed to find time to do one full revolution
so
C = 17907.1m
T = C/v = 162.8s
