Question

What is the volume of this cylinder? ​ 6m, 7m

Answer 1

`198\:\mathrm{m^3}`

Explanation:

The volume of a cylinder is given by
`V=r^2\pi\cdot h`, where
`r` is the radius of the cylinder and
`h` is the height.

What we're given:

• 
  `r` of 3
• 
  `h` of 7

Substituting given values, we get:

`V=3^2\pi\cdot 7,\\V=9\cdot 3.14\cdot 7,\\V\approx 197.82\:\mathrm{m^3}=\boxed{198\:\mathrm{m^3}}`, rounded the nearest cubic meter as requested in question.

Answer 2

Volume of cylinder is 197.82 m ³.

Explanation:

Here,

We have given that

Diameter of cylinder = 6 m

So, Radius of cylinder, r = 6 / 2 = 3m

Height of cylinder , h = 7 m

Value of π = 3.14

To find :-

Volume of cylinder

Solution :-

We know that,

Volume of cylinder = π × r ² × h

Substitute the values

Volume of cylinder = 3.14 × ( 3m ) ² × 7 m

volume of cylinder = 3.14 × 9m² × 7 m

Multiply , we get

Volume of cylinder = 197.82 m ³

Therefore, The volume of cylinder id 197.82 m ³.
