We know that circumference of circle = 2pir.
(1) Given radius = 7cm.
circumference of circle = 2 * 22/7 * 7
= 44cm.
(2) Given radius = 14cm.
the circumference of the circle = 2pir
= 2 * 22/7 * 14
= 88cm.
(3) Given radius = 21cm.
the circumference of the circle = 2pir
= 2 * 22/7 * 21
= 132cm.
Hope this helps!

Circumference of circle when radius is 7 cm = 2πr = 2*22/7*7 = 44 cm
Circumference of circle when radius is 3.5 cm = 2πr = 2*22/7*3.5 = 22 cm
Circumference of circle when radius is 14 cm = 2πr = 2*22/7*14 = 88 cm
Circumference of circle when radius is 21 cm = 2πr = 2*22/7*21 = 132 cm
Circumference of circle when radius is 3.5 cm = 2πr = 2*22/7*3.5 = 22 cm
Circumference of circle when radius is 14 cm = 2πr = 2*22/7*14 = 88 cm
Circumference of circle when radius is 21 cm = 2πr = 2*22/7*21 = 132 cm
