4P2 * 2P1 * 3P2
you want to use permuations instead of combinations because order matters.
12*2*6=144
Volume of the original sphere:
Volume = 4/3πr^3
Original sphere has a radius of 8 cm:
Volume = 4/3 * 3.14 * 8^3
Volume = 4/3 * 3.14 * 512
Volume = 2143.57 cubic cms.
Volume of smaller sphere with radius of 2 cm:
Volume = 4/3 * 3.14 * 2^3
Volume = 4/3 * 3.14 * 8
Volume = 33.49 cubic cms.
Number of balls that can be made: 2143.57 / 33.49 = 64
0.06666 is 1/15 as a decimal
