A cylinder is being filled with sand weighing 200 kg per cubic foot. The cylinder has a diameter of 1 foot and is 5 feet tall. How much sand is being used??  Options:
A) 250pi kg B) 500pi kg C) 500pi^2 kg D) 1000pi kg E) 1000pi^2 kg
Answer is A.   Volume of Cylinder = Pi*r^2 *h --------&gt; Pi * (1/2)^2 * 5 --------&gt; Pi * (1/4) * 5 --------&gt; (5/4)Pi cubic feet.   1 cubic feet = 200 kg. so (5/4)Pi cubic feet = ((200*5)/4)Pi ---------&gt; 250Pi   Regards,   250pi kgbhijit answer is 250pi kg
