Question

A rectangle piece of metal sheet 11 m × 4 m is folded wirhout overlapping to make a cylinder of height 4 m find the volume of the cylinder

Answer 1

Hello friend..


By the help of paper radius - 7/11 can we taken by split 2 pi r


Therefore volm of cy.

Pi r sq h

Putting values..

56/11 sq units . Is the anser




Hope it helps....

Thanks.

Answer 2

area of rect..l*b=44cm²
we have h = 4
so area of rect= vol of cylinder...
44=π*r²*h
44=(22/7)*r²*4
we get...r²=7/2..on solving
r=√7/2
...vol=(22/7)*(√7/2)²*4=44cm³..
hence vol of cyinder =area of rectangular sheet....
