Question

8.
If the area of the circular base of a cylinder is 22 cm and its height is
10 cm, then the volume of the cylinder is
​

Answer 1

Answer :-

• The volume of Cylinder is 220cm².

Step-by-step explanation:

To Find:-

• The volume of Cylinder

Solution:

Given that,

• The height of cylinder = 10cm
• The area of base of cylinder = 22cm.

∴ The radius of the cylinder

=> π(r)² = 22

=> π × r² = 22

=> 22/7 × r² = 22

=> r² = 22 × 7/22

=> r² = 1 × 7

=> r² = 7

To avoid approximation, the value of r is taken as r² = 7.

According the question,

• The volume of cylinder :-

We know that,

Volume of cylinder = πr²h cubic units,

Where,

• r = Radius
• h = Height

=> πr²h

=> π × r² × h

=> 22/7 × 7 × 10

=> 22 × 1 × 10

=> 22 × 10

=> 220cm²

Hence, The volume of Cylinder is 220cm².
