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:
Volume of a cone = (
)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 = ()πr2h
= ()(3.14)(4 x 4) (4)
= ()(3.14) (16 x 4)
= ()(3.14)(64)
= 200.
= 66.9 in3
Therefore correct option is b) 66.9 in3.
)(3.14)(4 x 4) (4))(3.14) (16 x 4))(3.14)(64)Therefore correct option is b) 66.9 in3.
