A cylindrical tank of radius 7 m has water to some level. If 110 cubes of side 7 cm are completely immersed in it, then find the rise in water level.

A cylinder of radius 24 cm. contains water to a depth of 40 cm. A spherical iron ball is dropped in to the cylinder and thus the level of water is raised by 13.5 cm. Find the radius of the ball. [pi=22/7]

A cyclinder of radius 12 cm. contains water to a depth of 20 cm. A spherical iron ball is dropped into the cylinder and thus the level of water is raised by 6.75 cm. Find the radius of the ball. [pi=22/7]

A cylindrical vessel with internal diameter 10 cm and height 10.5 cm is full of water. A solid cone of base diameter 7 cm and height 6 cm is completely immersed in water. Find the volume of water displaced out the cylinder Left in the cylinder.

A cylindrical well of radius 2.5 m has water upto a height of 14 m from the bottom. If the water level is at a depth of 6 m from the top of the well, then the time taken ( in minutes ) to empty the well using a motor of 10 HP is approximately, (Take, g = 10 ms^(-2) )

Spherical marbles of diameter 1.4 cm. are dropped into a cylindrical beaker of diameter 7 cm., which contains some water. Find the number of marbles that should be dropped into the beaker, so that water level rises by 5.6 cm.

A cylindrical tub of radius 5 cm and length 9.8 cm is full of water. A solid in the form of right circular cone mounted on a hemisphere is immersed into the tub. The radius of the hemisphere is 3.5 cm and height of cone outside the hemisphere is 5 cm. Find the volume of water left in the tub. " "("Take "pi=22/7)

Find the total surface area of the cube with side 7.5 cm.

A cylindrical vessel is filled with water upto the height 1 m from the base. A small orifice is opened at some height in the cylinder and the water level is reduced to height of orifice in 20 s. If the base area of the cylinder is 100 times the area of orifice, then the height of orifice from the base is (take, g = 10 m//s ^(2))
