The circumference of the circle is 28.26 in.
Step-by-step explanation:
Given,
The diameter of a circle = 9 in
Radius of the circle (r) = 4.5 in
To find the circumference of the circle.
Formula
The circumference of the circle of radius r = 2πr
Now,
The circumference of the circle = 2×3.14×4.5 in [ taking π = 3.14]
= 28.26 in
