Given:
a.) The diameter of a circle is 14 inches.
b.) Use 3.14 for л
For us to be able to determine the circumference of the circle using its diameter, we will be using the following formula:
[tex]\text{ Circumference = }\pi D[/tex]Where,
D = diameter of the circle
We get,
[tex]\text{ Circumference = \lparen3.14\rparen\lparen14\rparen = 43.96 cm}[/tex]Therefore, the circumference of the circle is 43.96 cm.
