Answer:

(i) 132 cm , (ii) 176 cm , (iii) 66 cm

Step-by-step explanation:

(i) r = 21

circumference of a circle = 2πr

= 2×22/7×21

= 44 × 3

= 132 cm

(ii) r = 28

circumference of a circle = 2πr

= 2×22/7×28

= 44 × 4

= 176 cm

(iii) r = 10.5

circumference of a circle = 2πr

= 2×22/7×10.5

= 44 × 1.5

= 66 cm
