Question

a rectangular piece of paper 11cm* 4cm is folded without overlapping to make a cylinder of height 4cm find the volume of the cylinder​

Answer 1

Answer:

Volume of the cylinder=38.5cm³

Step-by-step explanation:

Given:

A rectangular piece of paper 11cm×4cm is folded without overlapping to make a cylinder of height 4cm

The length of the paper becomes the circumference of the base of the cylinder and width becomes height

Let radius of the cylinder=r and height=h

Circumference of the base of cylinder=2πr=11cm

⇒$2×\frac{22}{7}×r=11$

∴$r=\boxed{\frac{7}{4}cm}$

Now, h=4cm

Volume of the cylinder( V )=πr²h

⇒$\frac{22}{7}×\frac{7}{4}×\frac{7}{4}×4cm^{3}$

⇒$\huge\boxed{38.5cm³}$

Therefore, the volume of cylinder=38.5cm³
