Question

a rectangular sheet of paper 44m,18cm,is rolled along its length and cylinder is


formed find the volume of cylinder

Answer 1

THANKS FOR THE QUESTION !

______________________________

GIVEN :

=> DIMENSIONS OF RECTANGULAR SHEET :

=> LENGTH :

=> 44M :

=> 44 * 100 CM

=> 4,400 CM

_______________________________

BREADTH :

=> 18CM

_______________________________

CONDITION :

=> SHEET IS ROLLED ALONG THE LENGTH :

=> CYLINDER IS FORMED :)

_______________________________

BY THE WHOLE INFO :

=> THE CIRCUMFERENCE OF THE BASE OF THE CYLINDER :

=> 4,400 CM

_______________________________

HEIGHT OF THE CYLINDER :

=> 18 CM

_______________________________

CIRCUMFERENCE OF THE CIRCLE :

=> 2πR

=> 2 * 22 / 7 * R

=> 44 * R / 7

_______________________________

BUT,

=> THE CIRCUMFERENCE IS GIVEN :

=> 4,400 CM

_______________________________

4,400 = 44 * R / 7

=> 4,400 * 7 / 44 = R

=> 700 CM = R

_______________________________

TO FIND :

=> VOLUME OF CYLINDER :

_______________________________

VOLUME OF A CYLINDER :

=> π * R^2 * H

=> 22 / 7 * 700 * 700 * 18

=> 22 * 100 * 700 * 18

=> 2,77,20,000 CUBIC CM

_______________________________

IN CUBIC M :

=> 2,77,20,000 C.CM / 10,00,000

=> 27.72 CUBIC M
