Find the exact volume of the cylinder.


Last one, for today!
Thanks! :)

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\\rightarrow \: (22)/(7) * {3}^(2) * 7}`

`\qquad{ \tt\\rightarrow \: (22)/( \cancel7) * {3}^(2) * \cancel7}`

`\qquad{ \tt\\rightarrow \: 22 * {3}^(2) }`

`\qquad{ \tt\\rightarrow \: 22 * 9 }`

`\qquad{ \boxed{ \tt\Rrightarrow \: 198\: {m}^(3) }}`

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