b) Radius = 6 cm .
Step by step explanation.
​

Answer 1

Step-by-step explanation:

this is the answer of this question

Answer 2

a) we have diameter = 9cm

. then, radius = diameter/2 = 9/2

. circumference of circle = 2πr

. = (2)×(22/7)×(9/2)

. = 198/7 cm

b) we have radius = 6 cm

. circumference of circle = 2πr

. = (2)×(22/7)×6

. = 264/7 cm
