How many spherical balls of radius 1 cm can be made by melting a hemisphere of radius 6cm?

112 108 116 104

108

Volume of a hemisphere = \(\frac{2}{3}\) \(\pi \) r3 = \(\frac{2}{3}\) \(\pi \) 63 Volume of a sphere = \(\frac{4}{3}\) \(\pi \) r3 = \(\frac{4}{3}\) \(\pi \) 13 No. of spherical balls = \(\frac{Vol.\;of\;hemisphere}{Vol.\;of\;sphere}\) = \(\frac{216}{2}\) = 108
