Answer 2

$\bf\bigstar{QUESTION}$

If diameter of cylinder is 8cm and it's height is 16cm then, what will be the volume of cylinder?​

$\bf\bigstar{ANSWER}$

Given :

Diameter of a cylinder = 8 cm

Height of the cylinder = 16 cm

To find :

Volume of the cylinder = ?

Solution :

Volume of the cylinder =

$\huge{\boxed{\boxed{\bf{Area\:x\:height}}}}}}$

For finding area, first we must calculate the radius of the cylinder.

$\longrightarrow\bf{Radius= \dfrac{1}{2}\:x\:Diameter}$

$\longrightarrow\bf{Radius= \dfrac{8}{2}}$

$\longrightarrow\bf{Radius= 4 \:cm}$

$\huge{\boxed{\bf{Area =\pi r^2}}}}$

$\bf{(\pi =3.14)}$

∴ Area = 3.14 x 4²

⇒ Area = 3.14 x 4 x 4

⇒ Area = 50.24 cm²

Height of the cylinder is already given that 16 cm.

$\huge{\boxed{\bf{Volume=area\:x\:height}}}}$

$\longrightarrow\bf{50.24\:x\:16\:cm^3}$

$\longrightarrow\bf{803.84\;cm^3}$

$\huge{\boxed{\boxed{\boxed{\bf{Volume=803.84\:cm^3}}}}}}}$

Hope this answer can helps u dear !! ♥
