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) }}}
