How long does it take a plane, traveling at a speed of 170 m/s, to fly once around a circle whose radius is 3500 m?
circumference = 2 pi r
so
2 pi r = 170 * t
To calculate the time it takes for a plane to fly once around a circle, we need to consider the distance and the speed of the plane.
The distance around a circle is given by the formula:
Circumference = 2 * π * radius
In this case, the radius is 3500 m. So, the circumference of the circle is:
Circumference = 2 * π * 3500 m
Now, we need to find the time it takes for the plane to cover this distance. We can use the formula:
Time = Distance / Speed
In this case, the distance is the circumference of the circle and the speed of the plane is given as 170 m/s.
Time = (2 * π * 3500 m) / (170 m/s)
To get the numerical value, we can plug this equation into a calculator and get the result.
So, the time it takes for the plane to fly once around the circle is approximately 123.53 seconds.
