note that when 10 kg of ice melts, it produces 10 kg of water
10 kg of water is 10 liters of water and
1 liter of water is 1000 cubic centimeters and
10 liters of water is 10,000 cubic centimeters, therefore
10000 = pi*r^2*30, where r is the radius of the cylindrical pail
pi*r^2 = 10000 / 30 = 333.333333333
r^2 = 333.333333333 / pi = 106.103295381
take square root of both sides of =
r = 10.300645387
diameter of cylindrical pail = 2*10.300645387 = 20.601290773 cm
