A cylinder has a radius of $$\frac{8}{\pi}$$ cm and its volume is 448 cm$$^3$$. What is the height of the cylinder (take $$\pi$$ = $$\frac{22}{7}$$​)?​

A cylindrical water tank has a base radius of 7 m and a height of 10 m. Water is filled into the tank at a constant rate. After filling the tank completely, 5% of the water leaks out due to a crack at the bottom. The remaining water is transferred into another cylindrical tank whose base radius is 5 m. Find the height of water in the second tank.

If the volume of a cone is 48π $$cm^3$$​ and the height is 10 cm . Find the radius of its base in nearest one decimal place.

The curved surface area of a cylinder having radius 5 cm and height 23 cm is:

Water flows out through a pipe, whose internal radius is 3 cm, at the rate of x cm per second into a cylindrical tank, the radius of whose base is 60 cm. If the level of water in the tank rises by 15 cm in 5 minutes, then the value of x is:

If the ratio of radii of the bases of two cylinders is 4 : 5 and the ratio of their heights is 5 : 2, then the ratio of their volumes is:

​ Find the volume of a cylinder with radius 5 cm and height 21 cm (use π = 22/7).

If the height of a cylinder is 16 cm and radius is 14 cm, what is the curved surface area (in cm²) of it?

The ratio of the radii of two cylinders is 2: 3 and the ratio of their heights is 5: 3. What will be the ratio of their curved surfaces?

A cylindrical tank has a capacity of 4774 m³. If the radius of the base is 7 m, what is the depth? (Use π = 22/7)

Find the volume of a cylinder with radius of base 7 cm and height 10.2 cm. (Use pi = 22/7)
