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 cm
^{3} - 75.4 cm
^{3} - 74.5 cm
^{3} - 75 cm
^{3}

^{3}^{3}^{3}^{3}Hint:

### Volume of a cone = ()πr2h

## The correct answer is: 75.4 cm^{3}

### 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 = ()πr^{2}h

= ()(3.14)(3 x 3)(8)

= ()(3.14) (9 x 8)

= ()(3.14)(72)

= 226.08 / 3

= 75.4 cm^{3}

Therefore, the volume of cone is 75.4 cm^{3}

Therefore correct option is b) 75.4 cm^{3}

^{3}

Therefore, the volume of cone is 75.4 cm

^{3}

Therefore correct option is b) 75.4 cm

^{3}
