Can someone help me please
Morgarella [4.7K]

Answer:

<u>The volume of this figure is approximately 418.88 centimeters squared!</u>

Step-by-step explanation:

The volume for a right circular cone is V = (π)(r^2)(h/3)

Substituting known values is as follows:

V = (π)(r^2)(h/3)

V = (π)(4^2)(25/3)

V = (π)(16)(25/3)

<u>V ≈ 418.88 cm^3</u>
