Question

Identify the volume of a cone with radius 6 m and height 11 m, rounded to the nearest tenth.

Answer 1

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}\qquad \begin{cases} r=radius\\ h=height\\ ----------\\ r=6\\ h=11 \end{cases}\implies V=\cfrac{\pi \cdot 6^2\cdot 11}{3}$

Answer 2

Cone Volume = (π • r² • h) ÷ 3

Cone Volume = PI * 6^2 * 11 / 3

Cone Volume = PI * 36 * 3.6666

Cone Volume = 414.69
answer is B.
