Question

What is the volume of the cone shown below?

Answer 1

Answer:

A. $96\pi \: cu. \: units$

Step-by-step explanation:

Radius of cone (r) = 4 units

Height of cone (h) = 18 units

$V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{3} \pi {(4)}^{2} \times 18 \\ \\ = \pi {(4)}^{2} \times 6 \\ \\ = 16\pi \times 6 \\ \\ V_{cone} = 96\pi \: {units}^{3}$
