Question
A cone has a base diameter of 6 cm and a vertical height of 8 cm. Calculate the volume of the cone in cubic centimetres.
- 74.4 cm3
- 75.4 cm3
- 74.5 cm3
- 75 cm3
Hint:
Volume of a cone = (
)πr2h
The correct answer is: 75.4 cm3
We have given the dimensions of a cone
Diameter = 6 cm
Radius , r = 
= 3 cm
Height , h = 8 cm
We have to find the volume of the given cone
We know that
Volume of a cone = ()πr2h
= ()(3.14)(3 x 3)(8)
= ()(3.14) (9 x 8)
= ()(3.14)(72)
= 226.08 / 3
= 75.4 cm3
Therefore, the volume of cone is 75.4 cm3
Therefore correct option is b) 75.4 cm3
)(3.14)(3 x 3)(8))(3.14) (9 x 8))(3.14)(72)Therefore, the volume of cone is 75.4 cm3
Therefore correct option is b) 75.4 cm3
