Question

14. A metallic cylinder of radius 8cm and height 18cm
is melted and recast into 16 cylinders of radius 2cm.
Find the height of each cylinder.​

Answer 1

Answer:

Step-by-step explanation:

volume of the cylinder = n(volume of small cylinder )

πr^h=n(πr^h)

22/7×8^×18=16(22/7×2^×h)

25344/7=16×88×h/7

25344=16×88×h

h=25344/16×88

h=18

Answer 2

Step-by-step explanation:

volume of the cylinder = n ( volume of the small cylinder)

π r^h = n (π r^ h)

22/7×8^×18 = 16 (22/7×2^×h)

25344/7= 16×88×h/7

25344 = 16 × 88 × h

h = 25344/16 × 18

h = 18
