Question

Find the diameter of a circle (in $cm$), if the radius is $6\mathrm{mm}$.

Answer 1

Given that

Radius = $6\mathrm{mm}$

As we know that, $Diameter=2\times Radius$

So,

$$\begin{gathered} \mathrm{Diameter}=2\times 6 \\ =12\mathrm{mm} \end{gathered}$$

Hence, the diameter of the circle is $12\mathrm{mm}.$
