Let the diameter of the smaller circle be x
Radius of bigger circle = diameter of smaller circle = x
6cm = radius of bigger circle + radius of smaller circle
= x + x/2
12cm = 3x
x = 4cm (radius of bigger circle)
Radius of bigger circle = diameter of smaller circle = x
6cm = radius of bigger circle + radius of smaller circle
= x + x/2
12cm = 3x
x = 4cm (radius of bigger circle)
