Question
A rectangular paper sheet of dimensions 33 cm x 14 cm is
folded along its length to form a cylinder. What will be the volume of this cylinder? Take γ =22/7Solution
Given β h= 1 4 cm 2Οr = 33 r = ( 33 Γ7)/22Γ2 = 21 / 4 cm volume of the cylinder = Ο r2h =22/7 Γ 441 / 16 Γ1 4 = 4851/4 cm3 =1212.75 cm3
