Question

find the volume of hemisphere of radius is 11.2​

Answer 1

Answer:-

$\pink{\bigstar}$Volume of the hemisphere with radius 11.2 cm is $\large\leadsto\boxed{\tt\purple{2943.8 \: cm^3}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Given :-

• Radius of the hemisphere = 11.2 cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• To Find :-

• Volume of the hemisphere ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Solution :-

We know,

$\pink{\bigstar}\:\large\underline{\boxed{\bf\green{Volume_{(hemisphere)} = \dfrac{2}{3} \pi r^3}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting in the Formula:-

$➪ \: \sf \dfrac{2}{3} \times \dfrac{22}{7} \times (11.2)^3$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$➪ \: \sf \dfrac{44}{21} \times (11.2)^3$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$➪ \: \sf \dfrac{44}{21} \times 1405$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$➪ \: \sf \dfrac{61820}{21}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\bigstar}$$\: \large{\bf\red{2943.8 \: cm^3}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the volume of the hemisphere is 2943.8 cm³
