Direction: Read the given information carefully and answer the following questions:
A square pyramid tank having the base side (A) meters and height (B) meters is completely filled with water. When a hemispherical tank of radius (C) meters is immersed in the square pyramid tank that is completely filled, the water spilled out is 19404 liters. The hemispherical tank is then taken out when completely filled by water. The remaining water in the square pyramid tank is poured in the cuboidal-shaped tank. The cuboidal shaped tank having the height of 3.83 m is completely filled. The ratio of the length and the breadth of the same cuboidal shaped tank is 3:5. The difference between the curved surface area and the total surface area of the cuboidal-shaped tank is 4.8 m2. The cylindrical tank is having a radius of equal to 1.4 meters more than (C) and its height is a tenth of the height of the pyramid shaped tank increased by 1 m. When the water from the square pyramid shaped tank is poured directly in the cylindrical shaped tank, the water spilled out is 28750 liters. The conical-shaped tank is approximately (D)% filled when the completely filled water in the cylindrical tank is poured in the conical shaped tank having the height equal to the radius of the hemispherical tank and radius equal to the slant height of the square pyramid shaped tank.
Assume the thickness of each of the tank is negligible. There is no water loss unless specified.
Find the approximate difference between the curved surface areas of the hemispherical shaped tank to that of the curved surface area of the cone?
Assume the height of the conical-shaped tank is negligible when compared to its radius.
