A rectangular piece of paper is 52 cm long and 18 cm wide. A cylinder is formed by rolling the paper along its breadth. Find the volume of the cylinder. [Taken $π =\frac{22}{7}$]
Answer & explanation
Correct answer: option 2
We already know that,
Volume of Cylinder = π r2 h,
Circumference of a Circle = 2 π r
So,
= 22 = 2 π r
= 22 = 2 × \(\frac{22}{7}\) × r
= r = \(\frac{7}{2}\)
Now the volume of a Cylinder = \(\frac{22}{7}\) × \(\frac{7}{2}\) × \(\frac{7}{2}\) × 52 = 2002 cm3
