Answer:

Circumference of a circle = pi * diameter

$219.8=3.14*d$

$d=\frac{219.8}{3.14}$

$d=70$

Radius = half of diameter

$r=\frac{1}{2} d$

$r=\frac{1}{2}*70$

$r=35$

Area of circle = $\pi r^2$ , where r is the radius:

$a=3.14*35^2$

$a=3846.5$

If they ran around the track 3 times, they would cover the circumference three times.

$219.8*3=659.4$

Convert to centimetres:

$659.4*100=65940$
