Question

Determine the volume of the cone

Answer 1

Option:-

• 
  `\large \underline{ \: \tt \red{ A ) 324π cm³\: }}`

`\:`

_________

Given:-

• 
  `\tt \: Radius=9cm`

`\:`

• 
  `\tt \: Height = 12cm`

`\:`

To find:-

• 
  `\tt \: volume \: of \: cone \: = \: ?`

`\:`

By using formula:-

`\small{\star \boxed{ \tt \color{blue} volume \: of \: cone \: = (1)/(3)h\pi {r}^(2) }}`

`\:`

Solution:-

• 
  `\tt \: v = (1)/(3)h\pi {r}^(2)`

`\:`

• 
  `\tt \: v = (1)/(3) * 12 * \pi * ( {9})^(2)`

`\:`

• 
  `\tt \: v = (1)/(3) * 12\pi * 81`

`\:`

• 
  `\tt \: v = \frac{1}{ \cancel{3} } * \cancel{972\pi}`

`\:`

• 
  `\underline{ \boxed{ \tt{ \color{hotpink} \: 324\pi \: {cm}^(3) }}}`

`\:`
