An architect built a scale model of a shopping mall. on the model, a circular fountain is 27 inches tall and 63 inches in diameter. if the actual fountain is to be 6 feet tall, what is its diameter? 14 ft 12 ft 2.6 ft 42 ft ! due !

The actual fountain is 6 ft tall1 ft = 12 inches...so 6 ft = (12 * 6) = 72 inches

72/27 = 2 2/3u have a scale factor of 2 2/3 (or 8/3)

so the diameter will be : 
63 * 2 2/3 =
63 * 8/3 =
504/3 =
168 inches12 inches = 1 ft...so 168 inches = (168/12) = 14 ft <==

X=3 and y=4 is the answer
