side of the cube is 9cm
⇒height of cone is 9cm
⇒radius of cone is 9/2 cm
Volume of remaining solid is volume cube - volume cone.
⇒a³-πr²h
⇒(9)³-22/7*9/2*9/2*9
⇒729-11/7*9*9/2*9
⇒729-99*81/14
⇒729-572.8
⇒156.2 cm³.

Answer:
diameter of cone = height of the cone = side of cube = 9cm
volume of cone = 1/3 × 22/7 × r × r × h
radius of cone = 9 / 2 cm
= 1/3 × 22/7 × 9/2 × 9/2 × 9
= 2673/14
=190. 9 cm cube
