Question

A cylinder has a radius 2.1cm and height 9cm find its volume ​

Answer 1

The volume of cylinder is 124.68981cm³

Step-by-step explanation: Given radius = 2.1cm and height = 9cm

therefore,

The volume of cylinder V

V= πr²h = πx(2.1)²x9 ≈ 124.68981 cm³

Answer 2

Answer:

=> 124.74 $cm^3$

Step-by-step explanation:

As per the data given in the question, we have to find the volume of a cylinder.

Given that:-

Radius = $2.1$ cm

Height = $9$ cm

As we know that,

The formula for the volume of a cylinder is $\pi r^2h$

Therefore,

$=>\frac{22}{7}\times (2.1)^2\times 9$

$=>\frac{22}{7}\times 4.41\times 9$

=> 124.74 $cm^3$

Hence, the volume of a cylinder is $124.74 cm^3$
