Radius (r) of given cylindrical wooden block = 3/2 cm (because Diameter = 2*radius) Length (h) = 20cm The volume of the block = πr²h = π *(3/2)²* (20) = 45 π Now we need to find max number of pieces of 1 cm in diameter. So, radius = 1/2 cm, length = 20cm So, volume of the required block = πr2h = π*(1/2)2*(20) = 5π So, max pieces = 45 π /5 π = 9 pieces.
A motor boat goes downstream from point A to B ,which is 36 km away from point A, and then returns to A. If actual speed of the boat in still water is 7...
