b)14cm

Circumference=2πr

=2*22/7*14

=2*22*2

=88cm

c)28cm

Circumference=2πr

=2*22/7*28

=2*22*4

=176cm

d)35cm

Circumference=2πr

=2*22/7*35

=2*22*5

=220cm

2:

a)14cm

Circumference=2πr

=2*22/7*14/2

=2*11*2

=44cm

b)28cm

Circumference=2πr

=2*22/7*28/2

=2*11*4

=88cm

c)56cm

Circumference=2πr

=2*22/7*56/2

=2*11*8

=176cm

d)70cm

Circumference=2πr

=2*22/7*70/2

=2*11*10

=220cm
