What is the exact volume of the cone in terms of pi?

kenny6666 [7]

Answer:

D) 3456 m

Step-by-step explanation:

Diameter of the cone = 48 m

Hence radius of the cone = $\frac{48}{2}$ = 24 m

Height of the cone = 18 m

Volume of a cone is given as $\[\frac{1}{3}*pi*radius^{2}*height\]
$

= $\[\frac{1}{3}*pi*24^{2}*18\]
$

= $\[\frac{1}{3}*pi*10368\]
$

= $\[pi*3456\]
$

Hence among the given options, option D is the correct one.
