Answer 1

Answer:

a circle inscribed in an equilateral triangle always divides it's median in the ratio 2:3

Step-by-step explanation:

its radius will be 2/3*median

Answer 2

The radius of circle is 6√3 cm.

Step-by-step explanation:

Since we have given that

Length of equilateral triangle = 18 cm

We need to find the radius of circle,

As we know that

$R=\dfrac{a}{\sqrt{3}}\\\\R=\dfrac{18}{\sqrt{3}}\\\\R=\dfrac{6\times 3}{\sqrt{3}}\\\\R=6\sqrt{3}$

Hence, the radius of circle is 6√3 cm.
