Question

it's very urgent
with proper explanation
question 16

Answer 1

if we rolled rectangular paper along it's length to form a cylinder then in this case height of this particular cylinder will be equal to the breadth of the paper and the circumference of it's base will be equal to the length of the paper,

then

circumference of base=22 cm,

2πr=22,

2×22/7×r=22,

then

r=7/2 cm

therefore
volume of the cylinder =πr²h,

=22/7 × 7/2 × 7/2 × 12,

=11×7×6,

=462 cm³
