In the given figure, the radius of the cone is same as its height equal to 2 cm each. The sum of the volumes of the whole body is :

1. 8π cm³

2. 16 cm³

3. 32π cm³

4. 32 cm³

In the given figure, height of the conical part is 3 cm. The radius and the height of the cylindrical part are 1 cm each. The total volume of the body is :

1. 9π cm³

2. 18π cm³

3. 2π cm³

4. 4π cm³

In the given figure, a solid cone is kept inverted in a closed cylindrical container such that the height of cone = height of cylinder = h, radius of cone = radius of cylinder = r and slant height of cone = l. If the remaining of cylinder is completely filled with water, the wetted surface area of the whole body is :

1. 2πrh + πr² + πrl

2. 2πrh + πrl

3. 2πrh + 2πr² + πrl

4. 2πrh - πr² + πrl
