Let radius of two circles be a( larger) and b
So 2 pi a = 2*2 pi b
a=2b
Area of larger circle
Pi a^2
Area of smaller circle
Pi b ^2
Pi 4 a^2
So area of larger circle is four times of smaller one
So 2 pi a = 2*2 pi b
a=2b
Area of larger circle
Pi a^2
Area of smaller circle
Pi b ^2
Pi 4 a^2
So area of larger circle is four times of smaller one
