Answer:
D = 3 cm
Step-by-step explanation:
Given that,
The circumference of a circle is 9.45cm.
We need to find the length of the diameter.
The formula for the circumference of a circle is given by :
[tex]C=2\pi r[/tex]
We know that, Diameter = 2r
So,
[tex]C=D\pi\\\\D=\dfrac{C}{\pi}\\\\D=\dfrac{9.45}{\pi}\\\\D=3\ cm[/tex]
So, the length of diameter is equal to 3 cm.
