A right circular cylindrical tank of 9 metre height is filled with water. Water comes out from there though a pipe having length of 6 cm diameter with a speed of 225 metre per minute and the tank becomes empty after 2 hrs. 24 minutes. Calculate the length of diameter.

A right circular cylindrical tank of 9 metres height is filled with water. Water comes out from there through a pipe having length of 6 cm diameter with a speed of 225 metre per minute and the tank becomes empty after 2 hours 24 minutes. Calculate the length of radius of the tank.

A right circular cylindrical tank of 9 metre height is filled with water. Whater comesout from there through a pipe having length of 6 cm diamter with a speed of 225 metres per minute and the tank becomes empty after 36 minutes. Calulate the length of radius of the tank.

A group of fire brigade personnel carried a right circular cylindrical tank filled with water and pumped out water at a speed of 420 metres per minute to put the fire in 40 minutes by three pipes of 2 cm diameter each. If the diameter of the tank is 2* 8 metres and its length is 6 metre, then calculate (a) what volume of water has been spent in putting out the fire and (b) hte volume of water that still remains in the tank .

Both ends of right circular cylindrical tank are semicircular . If diameter of the tank be 1.4 metre and length be 5 metre , then what will be the expenditure of colouring the external surface of the tank at the rate of Rs 10 per square - metre ?

If the surface area of a right circular cylindrical pillar is 264 sq-metres and volume is 396 cubic-metres, then calculate height and length of diameter of this pillar.

Height of a hollow right circular cylinder, open at both ends, is 2*8 metres. If length of inner diameter of the cylinder is 4*6 dcm and the cylinder is made up of 84*48 cubic-dcm of iron, then calculate the length of outer diameter of the cylinder.

Out of three jars of equal diameter and height, 2/3 part of the first, 5/6 part of the second and 7/9 part of the third were filled with dilute sulphuric acid. Whole of acid in the three jars were poured into a large jar of 2*1 dcm diameter, as a result the height of acid in the jar becomes 4*1 dcm. If the length of diameter of each of the three equal jars is 1*4 dcm. Calculate the height of three jars.

There are some water in a long gas jar of 7 cm diameter. If a solid right circular cylindrical pipe of iron having 5 cm length and 5*6 cm diameter be immersed completely in that water, calculate how much the level of water will rise.

The length of a cuboidal tank is 20 metres. The height of the water- level in the tank decreases by 15 cm when 18 kilolitres water is taken out from the tank. Then find the breadth of the tank.
