Explanation:
Height of triangle = (10√3)x(√3/2)=15
Distance between the centroid of the triangle and the vertex= 15 x 2/3 = 10
Since in-radius is one-third of the height of the triangle
therefore, length of the line from vertex to the point where small circle and big circle touch each other = 2x3 = 6
Radius of the bigger circle = 10 - 6 = 4cm
Ratio of areas will be square of the ration of radius which is 4:1.
