Question:
How many spherical bullets can be made out of a lead cylinder 28cm high and with radius 6 cm, each bullet being 1.5 cm in diameter?
A ) 1795
B ) 1892
C ) 1772
D ) 1792
Answer : D) 1792
Explaination :
Volume of cylinder = (∏ x 6 x 6 x 28) cm3
Volume of each bullet = ( 9∏/16) cm3.
Number of bullets =
The volume of cylinder /Volume of bullet
= [(36 x 28)∏ x 16] /9∏ = 1792.
