Answer
1.r = 11 m C= 69.08 m
Formula: C = 2πr
Solution:
C = 2 (3.14 x 11m)
C = 69.08 m
2.d = 2 cm C= 6.28cm
Formula: C = π d
Solution:
C = 3.14 x 2cm
C = 6.28 cm
3.d = 16 cm C= 50.24 cm
Formula: C = π d
Solution:
C = 3.14 x 16 cm
C = 50.25 cm
4. d = 20 m C= 62.8 m
Formula: C = π d
Solution:
C = 3.14 x 20 m
C = 62.8 m
5.r= 8 m C = 50. 24 m
Formula: C = 2 π r
Solution:
C = 2 x 3.14 x 8m
C = 50.24 m
Hope it helps
