Suppose the circular track in the figure below has a radius of 104 m and the runner has a speed of 3.3 m/s.
To calculate the time it takes for the runner to complete one lap around the circular track, we need to use the formula for the circumference of a circle:
Circumference = 2 * π * radius
Given that the radius of the circular track is 104 m, we can substitute this value into the formula:
Circumference = 2 * π * 104
Next, we can calculate the time it takes for the runner to complete one lap by dividing the circumference by the runner's speed:
Time = Circumference / Speed
Substituting the values we have:
Time = (2 * π * 104) / 3.3
To get the final answer, we can evaluate this expression using a calculator or software that can handle mathematical functions.
