Answer: 88 inches
Step-by-step explanation:
We know that the formula to find the circumference of circle is given by :-
[tex]C=2\pi r[/tex], where r is the radius of the circle.
Given : Diameter of circle = 28 inches
Also, diameter is twice of radius.
i.e. 2r=28
Therefore, the circumference of circle will be :-
[tex]C=2\pi r=(2r)\pi=28\times(3.14)=87.92text{ inches}\approx88\text{ inches}[/tex]
Hence, the circumference of circle is 88 inches.
