Question
How many spherical bullets can be made out of a lead
cylinder 45 cm high and 27 cm radius, each bullet being 3 cm in diameter?Solution
Volume of cylinder = π x r 2 x h = π x 272 x 45 & Volume of each bullet = (4/3) x π x (1.5)3 So number of bullets = Volume of cylider/volume of 1 bullet = (π x 272 x 45)/((4/3) x π x (1.5)3 ) = 7290
