Question

The circumference of a circle is 9.45cm.

Answer 1

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 :

$C=2\pi r$

We know that, Diameter = 2r

So,

$C=D\pi\\\\D=\dfrac{C}{\pi}\\\\D=\dfrac{9.45}{\pi}\\\\D=3\ cm$

So, the length of diameter is equal to 3 cm.
