390cm but most running tracks have 8 lanes
From the staggered start, it is 400 meters around. The stagger is calculated by subtracting the extra distance one goes around a wider diameter. For each lane it is double the lane width (which in the Olympics is 1.22m) times pi. for each additional lane.
65cm is equivalent to 0.65 meters.
To find the fraction of one meter that 65cm represents, we need to convert 65cm to meters. Since 1 meter is equal to 100cm, 65cm is equal to 0.65 meters. Therefore, the fraction of one meter that 65cm represents is 0.65/1, which simplifies to 13/20. So, 65cm is 13/20 of one meter.
38cm + 65cm + 47cm = 150cm
0.65m
The circumference of a circle of 65cm radius is about 408.41cm(Circumference = 2*pi*65 cm)
