The in-radius of an equilateral traingle is of length 3 cm. Then the length of each of its medians is :
The in-radius of an equilateral traingle is of length 3 cm. Then the length of each of its medians is :
[A]4 cm
[B]9 cm
[C]9.5 cm
[D]12 cm
9 cm
In the equilateral triangle centroid, incentre, orthocentre, coincide at the same point.
∴ Height 
∴ Height = Median = 3
Hence option [C] is the right answer.
