If the incentre of an equilateral triangle lies inside the triangle and its radius in 3 cm, then the side of the equilateral triangle is
A. 9$$\sqrt 3 $$ cm
B. 6$$\sqrt 3 $$ cm
C. 3$$\sqrt 3 $$ cm
D. 6 cm
Answer: Option B
Solution (By Examveda Team)
Inradius = $$\frac{a}{{2\sqrt 3 }}$$ (a = side of Δ)3 = $$\frac{a}{{2\sqrt 3 }}$$
a = 6$$\sqrt 3 $$ cm
