Answer 1

$\mathcal \pink{GIVEN:}$

• Radius = 3 m
• Height = 7 m

$\mathcal \purple{TO \: FIND:}$

• Volume = ?

$\mathcal \blue{CALCULATION:}$

$\qquad{ \sf \: volume = \pi{r}^{2}h }$

Where,

• r is radius
• h is height

$\qquad{ \tt\nrightarrow \: \frac{22}{7} \times {3}^{2} \times 7}$

$\qquad{ \tt\nrightarrow \: \frac{22}{ \cancel7} \times {3}^{2} \times \cancel7}$

$\qquad{ \tt\nrightarrow \: 22 \times {3}^{2} }$

$\qquad{ \tt\nrightarrow \: 22 \times 9 }$

$\qquad{ \boxed{ \tt\Rrightarrow \: 198\: {m}^{3} }}$

➪ Henceforth, The volume of the cylinder is 198 m³...
