Question

find the capacity of a cylinder whose diameter is 70 cm and height is 1.4 m

Answer 1

Answer :

Capacity of the cylinder is 539000 cm³

Step-by-step explanation:

• Diameter of the Cylinder,D = 70cm

• Radius of the Cylinder,r = D/2 = 35 cm

• Height of the Cylinder,h = 1.4 m = 140 cm

Capacity of a cylinder refers to its Volume

$\boxed{\boxed{\sf{Volume \ of \ a \ Cylinder = \pi r^2 h}}}$

Substituting the values,we get :

$\longrightarrow \: \sf \: \dfrac{22}{7} \times 35 {}^{2} \times 140 \\ \\ \longrightarrow \: \sf \: 20 \times 22 \times 1225 \\ \\ \longrightarrow \: \underline{ \boxed{ \sf{539000 \: {cm}^{3} }}}$

Answer 2

Answer :

• Capacity of cylinder = 539,000 cm³

Given :

• Diameter = 70 cm

• Height = 1.4 m

To find :

• The capacity of cylinder = ?

Step-by-step explanation :

Here,

Diameter = 70 cm

∴ Radius = Diameter /2 = 70/2 = 35 cm

Height = 1.4 m = 1.4 × 100 = 140 cm

Now,

The capacity of cylinder = Volume of cylinder

So, Volume of cylinder = Πr²h

Substituting the values in the above formula, we get

= 22/7 × 35 × 35 × 140

= 22 × 5 × 35 × 140

= 539,000 cm³

Thus, the capacity of the cylinder = 539,000 cm³.
