Subtract the volume of the hole from the volume of the ball. The volume of a ball is given by the formula V = (4/3)πr^3, where r is the radius.
Volume of the ball = (4/3)π(12^3)
Volume of the hole = (4/3)π(9^3)
To find the volume of the resulting solid, we subtract the volume of the hole from the volume of the ball:
Volume of resulting solid = Volume of the ball - Volume of the hole
Now you can calculate the volume of the resulting solid using the given values.
