Question

Find the volume of the largest right circular cone that can be cut out of cube whose edge is 4.2cm

Answer 1

SINCE CONE IS BIENG CUT FROM CUBE

THEREFORE THE RADIUS OF THE CONE 4.2/2=2.1CM AND HIEGHT IS 4.2CM

THREFORE

VOL. OF CONE =1/3×22/7×2.1×2.1×4.2

=19.404 CUBIC CM

HERE IS YOUR ANSWER

Answer 2

Answer:

19.404 cm

Step-by-step explanation:

The cube has sides of 4.2 cm. Its volume = 4.2^3 = 74.088 cc.

The largest cone that can be carved out of the cube is one whose base diameter is 4.2 cm and the height is 4.2 cm.

The volume of the cone will be (1/3)(22/7)*2.1^2*4.2

= 19.404 cm
