Question

What is the volume of the cone to the nearest cubic meter? (Use π = 3.14) A)21 m3 B)84 m3 C)168 m3 D)335 m3

Answer 1

Given:

The height of the cone, h=5m.

The radius of the base of the cone, r=4 m.

The volume of the cone can be calculated as,

`\begin{gathered} V=(1)/(3)\pi r^2h \\ V=(1)/(3)*\pi*4^2*5 \\ V=(1)/(3)*3.14*16*5 \\ V\approx84m^3 \end{gathered}`

Therefore, the volume of the cone is 84 cu.m.

Hence, option B is correct.
