​

Answer 1

Answer:

Given the radius of base of the circular cylinder is (r)=5 cm.

And the height of the cylinder is given to be (h)=12 cm.

So the volume of the cylinder is V

1

=πr

2

h=300π cm

3

.

Also given the radius of the conical cavity is r=5 cm.

And height is also given to be (h)=12 cm.

So its volume is V

2

=

3

1

πr

2

h=100 cm

3

.

So the volume of the remaining solid is V

1

−V

2

=(300−100)π=200π cm

3

.
