$180ft^{3}$

Step-by-step explanation:

Volume of a cone:

$V=\pi r^{2} \frac{h}{3}$

Take $\pi$ as 3, as mentioned in the question

'r' is 'radius' ⇒ {diameter is given so divide by 2: 12/2 = 6}

'h' is 'height'

$V=(3)(6)^{2} (\frac{5}{3} )$

$V=(3)(36)(\frac{5}{3} )$

$V=108(\frac{5}{3} )$

{multiply 108 with 5 and then divide the answer by 3}

V=108 ×

V=540

V=540/3

$V=180ft^{3}$
