Question

8 Find the volume of the right circular
cone with radius 6 cm and height 7 cm
O 265 cube cm
266 cube cm
O 264 cube cm
O 285 cube cm​

Answer 1

ANSWER:

• Volume of the cone = 264 cm²

GIVEN:

• Radius of the cone = 6 cm

• Height of the cone = 7 cm

TO FIND:

• Volume of the right circular cone

EXPLANATION:

$\boxed{\boxed{\large{\bold{Volume \ of \ cone =\dfrac{1}{3} \pi r^2h}}}}$

r = 6 cm

h = 7 cm

Volume of the cone = 1/3(22/7 × 6 × 6 × 7)

Volume of the cone = 1/3(22 × 36)

Volume of the cone = 22 × 12 m²

Volume of the cone = 264 cm²

SOME INTERESTING POINTS ABOUT CONE:

• Volume of cone = 1/3 πr²h

• Volume of cylinder = πr²h

Consider a cylinder and a cone having same height and same base radius. Then the volume of cone will be equal to three times the volume of the cylinder. This is experimentally proved.
