Work out the circumference of this circle.Take pi to be 3.142 and give your answer to 1 decimal place .The radius is 9cm .??

Answer:
=28.3m
Step-by-step explanation:
Circumference of a circle = 2πr
Where π= 3.142
From the diagram diameter = 9m
Radius = diameter/2
R = 9/2
R = 4.5m
Circumference = 2×3.142×4.5
Circumference = 28.278
=28.3m
