Question

A solid is in the form of right circular cone is mounted in a hemisphere.The radius of hemisphere is 4.2 and the height of the cone is 8cm. the solid in a cylindrical tub fell water in such a way that whole solid is submerged in the water. If the radius of the cylinder is 10cm and its height is 19.6 cm find the volume of water left in the cylindrical tub

Answer 1

Answer:The volume of the water left in the cylinder tub is 5934.544cm cube.

Step-by-step explanation:

Total volume of the solid is : (1/3 x 22/7 x 4.2 x 4.2 x 8) + (2/3 x 22/7 x 4.2 x 4.2 x 4.2)

     = 147.84 + 77.616

     = 225.456

Volume of the cylinder : 22/7 x 10 x 10 x 19.6

                                         = 6160

Volume of water left is : 6160 - 225.456

                                  = 5934.544
