Question

A silver cylinder of diameter 20 cm and height 15 cm is converted into a rod of length 60 cm of uniform thickness. Find the thickness of the rod.

Answer 1

Answer:

Step-by-step explanation:

d = 20 cm

r = 10 cm

h = 15 cm

h2= 60 cm

thickness = pie * r2^2

pie* 100 * 15 = 60 * pie * r2^2

r2 = 5 cm

d2 = 10cm

thickness = pie * 25

= 25 pie

= 78.5 cm
