Question : 111 of 200

Marks: +1, -0

A rectangular tin sheet is 12 cm long and 5 cm broad. It is rolled along its length to form a cylinder by making the opposite edges just to touch each other. Then the volume of the cylinder is

${60}/π$ $cm^3$
${180}/π$ $cm^3$
${120}/π$ $cm^3$
${100}/π$ $cm^3$

Validate

Solution:

Circumference of base of cylinder = 12 cm.
∴ 2πr = 12
⇒ r =

{12}/{2π}

6/π

cm
Height = 5 cm
∴ Volume of cylinder =

πr^2h

= π ×

6/π × 6/π

× 5 =

{180}/π

cu. cm.
