Hi Kaeruno,

The radius of the stool is 21 cm. To find the circumference, multiply this by 2 pi, since multiplying by 2 gives you the diameter and multiplying that by pi give the circumference.

2pi * 21cm

= pi * 2 * 21cm

= pi * 42cm

= (22/7) * 42cm

= 924/7 cm

= 132 cm.

The circumference is 132 cm.
