Answer 2

GiveN:-

Milk powder comes in a cylindrical container whose base has a diameter of 14cm and height of 20 cm.

To FinD:-

Find its volume.

SolutioN:-

• We know that radius is half of diameter.
• So, radius = diameter/2 = 14/2 = 7 cm
• Radius = 7 cm.

We know that,

$\large{\green{\underline{\boxed{\bf{Volume=\pi\:r^2h}}}}}$

where,

• r is radius = 7 cm
• π = 22/7
• h is height = 20 cm

Putting the values,

$\large\implies{\sf{Volume=\dfrac{22}{7}\times(7)^2\times20}}$

$\large\implies{\sf{Volume=\dfrac{22}{7}\times7\times7\times20}}$

$\large\implies{\sf{Volume=\dfrac{22}{\cancel{7}}\times\cancel{7}\times7\times20}}$

$\large\implies{\sf{Volume=22\times7\times20}}$

$\large\therefore\boxed{\bf{Volume=3080\:cm^3.}}$

The volume is 3080 cm³.
