Answer:

Answer in terms of π=144π m^3

Answer by replacing π with 3.14 is 452.16 approximately 452.2m^3

Answer to the nearest whole no. is 452m^3

Step-by-step explanation:

$volume \: of \: a \: cone = \frac{1}{3} \pi {r}^{2} h$

$radius = \frac{diametre}{2}$

$radius = 24$

$height = 18$

$slant \: height \: = 30$

$first \: step$

$the \: exact \: volume \: of \: the \: cone \: in \: terms \: of \: \pi$

$v = \frac{1}{3} \pi {r}^{2} h$

$\: \: = \frac{1}{3} \times \pi \times 24 \times 18$

$\: \: \: = \frac{432\pi}{3}$

$\: \: \: = 144\pi$

$second \: step$

$approximate \: answer \: using \: 3.14 \: in \: place \: of \: \pi$

$144 \times 3.14$

$= 452.16$

$approximately \: 452.2$

$last \: step$

$answer \: to \: the \: nearest \: whole \: number$

$452 {m}^{3}$
