Question

Help me with number 6 please thanks just need answer no need explanation n

Answer 1

Given: A cone of the height of 15 meters and base diameter of 40 meters.

Required: To determine the volume of the cone.

Explanation: The volume of the cone is given by-

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

Here,

$\begin{gathered} h=15\text{ m} \\ r=\frac{40}{2}=20\text{ m} \end{gathered}$

Hence, the volume of the cone is-

$V=\frac{1}{3}\times3.14\times(20)^2\times15$

Further solving as-

$\begin{gathered} V=3.14\times400\times5 \\ =6280\text{ m}^3 \end{gathered}$

Final Answer: Option B is correct.
