Answer:
(D) is correct
Step-by-step explanation:
Given: A circle with diameter 8.4 centimeters.
To find: The circumference of the given circle.
Solution: It is given that a circle has a diameter of 8.4 cm, therefore radius of the circle will be:
[tex]R=\frac{D}{2}=\frac{8.4}{2}=4.2 cm[/tex].
Now, the circumference of the circle is given as:
[tex]C=2{\pi}r[/tex]
Substituting the given values, we have
[tex]C=2{\pi}(4.2)[/tex]
[tex]C=8.4{\pi} cm[/tex]
Thus, the circumference of the circle will be [tex]8.4{\pi} cm[/tex].
