$\tt{\huge{\orange {Hello!!! }}} B.Q$

QUESTION :

Find the volume of hemisphere whose radius is 126 cm .

SOLUTION :

We know That :

$\tt{\purple{\leadsto{Volume \: Of \: A \: Hemisphere = \dfrac{2}{3} \pi \: {r}^{3} }}}$

$\tt{\mapsto{\red{Given \: - \: r = 26 \: cm. }}}$

Substituting this value into the above Equation ,

$\tt{\blue{\leadsto{ \dfrac{2}{3} \pi \: {(126)}^{3} = \dfrac{2}{3} \times 3.14 \times 126 \times 126 \times 126 = 4187453.76 \: {cm}^3 }}}$

___________

A n S w E r :

The volume of the required hemisphere is 4187453.76 cm^3.
