Circumference of outer ring = 110 cm
=> 2 * pi *r = 110
=> 2*22 *r/7 = 110
=> r = 110 * 7 / 44
=> r = 70/4
=> r = 35/2
=> r = 17.5 cm
Radius of outer ring = 17.5 cm
Circumference of inner ring = 88 cm
=> 2 pi r = 88
=> 2 *22r/7 = 88
=> r = 88 * 7/44
=> r = 2*7
=> r = 14 cm
Width between rings = 17.5 - 14
= 3.5 cm
=> 2 * pi *r = 110
=> 2*22 *r/7 = 110
=> r = 110 * 7 / 44
=> r = 70/4
=> r = 35/2
=> r = 17.5 cm
Radius of outer ring = 17.5 cm
Circumference of inner ring = 88 cm
=> 2 pi r = 88
=> 2 *22r/7 = 88
=> r = 88 * 7/44
=> r = 2*7
=> r = 14 cm
Width between rings = 17.5 - 14
= 3.5 cm
