A formula for the volume, V, of a right circular cylinder is V = πr^2h, where r is the radius and h is the height. The cylindrical tank shown below has a radius of 5 meters and a height of 4 meters and is filled with water. If 1 cubic meter of water weighs approximately 2,205 pounds, then the weight, in pounds, of the water in the tank is: ( ) A. less than 200,000. B. between 200,000 and 400,000. C. between 400,000 and 600,000. D. between 600,000 and 800,000. E. more than 800,000.

The diameter of a cylindrical water tank is 8 ft, and its height is 7 ft. What is the volume of the tank? Use the value 3.14 for π, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer. 8 ft 7 ft
