Cone in cube

The cube is an inscribed cone. Determine the ratio of the volume of the cone and cube.

Please write the ratio as a decimal number and as a percentage.

Correct answer:

r =  0.2618
r₂ =  26.2 %

Step-by-step explanation:

$$\begin{gathered} r=V_1:V_2 \\ r=\frac{\pi }{12}=\frac{3.1416}{12}=0.2618 \end{gathered}$$

$r_2=100\cdot r=100\cdot 0.2618=26.2\%$
