We know that perimeter of rectangle = curved surface area of cyclinder therefore perimeter of rectangle = 2( l+b) = 2 ( 66 +12 ) = 2 ( 78 ) =156 cm curvd surface area of cylinder = 2πrh now ...we will compare perimeter and csa and find value of r 2 x 22 x r x 12 = 156 7

=R = 156 x 7 2 x 22 x 12 =91 44 value of r = 2.06 cm

now volume of cylinder = πr2h......................this means that pie ..square of radius and height of cyclinder

value of pie is 22/7

= 22 x 206 x 12 = 77.69 cm is volume of cyclinder 7 x 100
