A fist looking from within water sees the outside world through a circular horizon. If the fish `sqrt(7)` cm below the surface of water, what will be the radius of the circular horizon

A fish looking up through the water sees the outside world contained in a circular horizon.If the refractive index of water is 4//3 and fish is 12 cm below the surface of water,then the radius of the circular horizon is

A fish, looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is 4/3 and the fish is 12 cm below the surace of water, the radius of the circle in centimere is
