The radius of a sphere and the radius of the base of a right circular cylinder are equal to r. If the ratio of the volume of the sphere to that of the cylinder is 8 : 3 then the height of the cylinder is

The radius of a roller is 35 cmand its length of 3 meters. The area (in sq.mts) it covers in 25 rounds is (Take $$\pi = \frac{22}{7}$$).
