Question

# What is the volume of a cone having radius of 21cm and height of 5cm?

- 2310cm
^{3} - 2500cm
^{3} - 6930cm
^{3} - 7500cm
^{3}

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

### Volume of a cone = (1/3)πr2h

## The correct answer is: 2310cm^{3}

### We have given the dimensions of a cone

Radius , r = 21 cm

Height , h = 5 cm

We have to find the volume of the given cone

We know that

Volume of a cone = (1/3)πr^{2}h

= ()()(21 x 21) (5)

= ()(22)(3 x 21) (5)

= (22 x 21 x 5)

= 2310 cm^{3}

Therefore correct option is a) 2310cm^{3}

^{2}h

^{3}

Therefore correct option is a) 2310cm

^{3}
