Explain and correct the error in the example above

Answer:
C = 28.26 cm
Step-by-step explanation:
The figure shows a circle of diameter 9 inches.
The person has taken radius r as 9 inches which is wrong.
The radius must be (9/2) = 4.5 inches, such that,
Circumference = 2πr
= 2×3.14×4.5
= 28.26 cm
Hence, this is the required solution.
