Question

in the cylindrical container the base radius is 8cm .if the height of the water level is 20cm ,find the volume of the water in the container ​

Answer 1

Answer:

4021.24 cm³

Step-by-step explanation:

cylinder volume formula = π*radius²*height

your answer: π*8²*20 = 4021.24 cm³

Answer 2

$\large{\underline{\underline{\textsf{\maltese\: {\red{Given :-}}}}}}$

☞ Radius (r) = 8cm

☞ Height (h) = 20cm

$\large{\underline{\underline{\textsf{\maltese\: {\red{To Find :-}}}}}}$

☞ Volume (v) of the water in the container = ?

$\large{\underline{\underline{\textsf{\maltese\: {\red{Solution :-}}}}}}$

Volume of cylinder = πr²h

✿ Putting the values.

Volume of cylinder = πr²h

⇒ Volume of cylinder =  $\dfrac{22}{7}$ × 8 × 8 × 20

⇒ Volume of cylinder = 4,022.8cm³

✿ Now we change the unit.

1000cm³ = 1L

⇒ 1cm³ = $\dfrac{1}{1000}$ L

⇒ 4,022.8 cm³ = $\dfrac{1}{1000}$ × 4,022.8 L

⇒ 4,022.8cm³ = 4.0228 L

Therefore, the volume of the water in the container is 4.0228 litres.
