why are not rainbows circular in shape? why aren't small rainbows formed around fountains circular in shape?

Rainbows are indeed circular in shape. The horizon blocks part of the rainbow and only an arc is seen. As one goes higher into the atmosphere a circular rainbow could be seen.
The fountains or waterfalls are of relatively small size, so they block only a part of the sunlight, and hence form only arcs of rainbow and not full circles.
