id cylinder of radius 15 cm and height 32 cm is melted and some small cylinders of radius 3 cm
isht 8 cm are formed. Find the number of small cylinders formed.​

Answer 1

Answer:

100

Step-by-step explanation:

volume of big cylinder=πr^2h=π*225*32=7200π

small cylinder=π*9*8=72π

big cylinder=n*small cylinder

n=7200π/72π

n=100
