A hemispherical bowl of internal radius 9 cm is full of liquid. The liquid is to be filled into cylindrical bottles of radius 1.5 cm and height 4 cm. How many bottles are needed?
A54
B36
C48
D72
✓ Correct Answer: A — 54
Vol bowl = 2/3π(9³). Vol bottle = π(1.5)²(4). N = (2/3 * 729) / (2.25 * 4) = 486 / 9 = 54.
