What is the volume of a cone having radius of 21cm and height of 5cm?
- 2310cm3
- 2500cm3
- 6930cm3
- 7500cm3
Hint:
Volume of a cone = (1/3)πr2h
The correct answer is: 2310cm3
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)πr2h
= (
)(
)(21 x 21) (5)
= ()(22)(3 x 21) (5)
= (22 x 21 x 5)
= 2310 cm3
Therefore correct option is a) 2310cm3
)()(21 x 21) (5))(22)(3 x 21) (5)Therefore correct option is a) 2310cm3
