A hemispherical tank has inner radius of 2.8 m. Find its capacity in litres​.

$\underline{\boxed{\bold{ \bigstar \; Answer \; \bigstar }}}$ $\; \; \; \;$

Given:-

Inner radius = 2.8 m

We know that,

Volume of hemisphere = $\frac{2}{3} \pi$r³

                                       = ($\frac{2}{3}$) ($\frac{22}{7}$) (2.8)³

                                       = 45.99 m³ (approx.)

1 m³ = 1000 l

  = (45.99) (1000)

  = 45990 l

★ NOTE -

• Be careful while converting the units.
• Pay special attention to what the question demands.
• Learn the conversion table.

Hope this helps uh! ♡

Answer 2

Answer :-

Volume of hemisphere = 2/3 π r³

↝ (2/3) (22/7) (2.8)³

↝ 45.99 m³ (approx.)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀→ 45.99 or 46 Ans.
