Question

a hollow metallic cylinder is made from a mettalic sheet of 2.6 cm thickness the outer radius of the cylinder is 3.8 cm and length is 50 m. Find the volume of the cylinder
(use pie as 3.14)(see the lenght is in m but others are in cm)

Answer 1

r=1.2
R=3.8
h=5000
therefore volume of the hollow cylinder =
π(Rsquare-rsquare)height
= 22/7*((3.8)square-(1.2)square)*5000
=22/7(14.44-1.44)*5000
=π(13)5000
=65000πcm cube
is the volume of the hollow cylinder hope my answer meets your requirements. * is multiplication symbol
