Question

How many bullets can be made out of a lead cylinder of hieght 12cm and base radius of 5cm and the bullet having a base radius of 1.5cm?

Answer 1

We have given that,

height of the cylinder= 12cm.

radius of the cylinder= 5cm.

we know that,

volume of cylinder πr^h

so,

volume of the cylinder = 3.14×5×5×12

= 3.14×300

= 942

Now,

radius of the bullet= 1.5 cm

volume of bullet is 4/3πr3

numbers of bullets that can be obtained from the cylinder = 942/4/3×3.14×1.5×1.5×1.5

= 66.66

So,

67 bullets can be made from cylinder.

I HOPE IT WILL HELP YOU LOT.
