How long does it take a plane, traveling at a constant speed of 110m/s, to fly once around a circle whose radius is 2850m.

You need to use the formula for the circumference of a circle.
Circumference = 2 x 3.14159 x (radius)
Then use the constant-speed formula:
Time = distance / speed
You need to take care, that the distance and speed are in compatible units. If distance is in miles, then speed should be in miles per hour, and the time will be in hours.

Time is distance divided by speed. The distance is 2*pi*r. Finish the rest of this homework problem on your own.

time=distance/velocity
t=2*pi*r/110
t=2*3.14*285/11
