10cm and the height is 21cm. (Take T=22/4)

Answer 1

Question:

Find the Volume of a Cylindrical Tank whose radius is 10cm and the height is 21cm. (Take π =
`{\bold{(22)/(7)}}`)

Answer:

We know that,

`\quad`
`\quad`
`{ \boxed{ \sf{Volume \: of \: Cylinder =\pi {r}^(2)h }}}`

➛
`{ \large{(22)/(7) * {(10)}^(2) * 21}}`

➛
`{ \large{ (22)/(7) * 10 * 10 * 21 }}`

➛
`{ \large{ (22)/(7) * 100 * 21 }}`

➛
`{ \large{ \frac{22}{{ \cancel{7}} ^(1) } * 100 * { \cancel{21}}^(3) }}`

➛
`22 * 100 * 3`

➛
`22 * 300`

➛
`{ \boxed{ \green{6600{ \rm{ {cm}^(3)}} }}}`

Thus, The volume of Cylindrical Tank is
`{ \bold{ \: 6600{ { \bold{ {cm}^(3)}} }}}`.
