Answer 1

Answer:

132 cm

Step-by-step explanation:

circumference=2πr

                       =2×22/7×21

                       =132 cm

Answer 2

Sooo easy .. comme on let's solve this

circumference =2 π r

so 2 x 22/7 x 21

=2 x 22 x 3

= 44 x 3

= 132

All you need to know is : CIRCUMFRENCE = 2πR:
