How many times, correct to the nearest whole number, will a man run round a circular track of diameter 100m to cover a distance of 1000m?

How many times, correct to the nearest whole number, will a man run round a circular track of diameter 100m to cover a distance of 1000m?

Answer Details

In terms of distance, a circle has a total distance or perimeter of 2π or π
Where r is radius and D is the diameter
So perimeter = $\frac{22}{7}$ x 100
= 314.2857m
To cover a distance of 1000m, he is going to round the circular track for $\frac{1000}{314.2857}$ = 3.18
It means it is on the number 4 round after the third round he is going to cover up to 1000m
