How long does it take a plane, traveling at a constant speed of 190 m/s, to fly once around a circle?

How long does it take a plane, traveling at a constant speed of 190 m/s, to fly once around a circle whose radius is 3350 m?How long does it take a plane, traveling at a constant speed of 190 m/s, to fly once around a circle?Hint acceleration is constant,

Dist=2pie R{R=3350m}
