Answer 2

Answer:

38.5 cm³

Step-by-step explanation:

Given, the length of rectangle as 11 cm becomes the circumference of the cylinder when folded without overlapping.

So,

$\implies$ $\sf{C = 2πr}$

$\implies$ $\sf{11= 2 × {\Large\frac{ 22}{ 7}} r }$

$\implies$ $\sf{ {\Large\frac{ 11×7 }{ 2×22 }} = r}$

$\therefore$ $\sf{ r ={\Large\frac{ 7 }{ 4}} }$

To find Volume:

$\implies$ $\sf{ V = πr^2h}$

$\implies$ $\sf{{\Large\frac{22 }{7 }}×({\Large\frac{ 7 }{ 4 }})^2 × 4}$

$\implies$ $\sf{ {\Large\frac{ 11×49 }{ 7×2 }}}$

$\therefore$Volume = $\boxed{\sf{ 38.5\: Cm^3 }}$
