Question

Find the volume of the cone. Round decimals nearest tenth. D = 12cm, h = 8 cm

3617.3 cm³
361.7 cm³
301.4 cm³
30.1 cm³

hint Hint:

Volume of a cone = ( $1 third$ )πr2h

The correct answer is: 301.4 cm³

We have given the dimensions of a cone
Diameter = 12 cm
Radius, r = $12 over 2$ = 6 cm
Height, h = 8 cm
We have to find the volume of the given cone
We know that
Volume of a cone = ( $1 third$ )πr²h
= ( $1 third$ )(3.14)(6 x 6) (8)
= ( $1 third$ )(3.14) (36 x 8)
= ( $1 third$ )(3.14)(288)
= 904. $32 over 3$
= 301.4 cm³
Therefore correct option is c) 301.4 cm³.
