Question

Find the volume of the cone. Use 3.14 for π. Round decimal answers to the nearest tenth. r= 4 in, height = 4 in

234.6 in³
66.9 in³
23.5 in³
17.6 in³

hint Hint:

Volume of a cone = ( $1 third$ )πr2h

The correct answer is: 66.9 in³

We have given the dimensions of a cone
Radius, r = 4 in
Height, h = 4 in
We have to find the volume of the given cone
We know that
Volume of a cone = ( $1 third$ )πr²h
= ( $1 third$ )(3.14)(4 x 4) (4)
= ( $1 third$ )(3.14) (16 x 4)
= ( $1 third$ )(3.14)(64)
= 200. $96 over 3$
= 66.9 in³
Therefore correct option is b) 66.9 in³.
