An architect built a scale of a shopping mall. On the model, a circular fountain is 10 inches tall and 20.5 inches in diameter. If the actual fountain is to be 8 feet tall, what is its diameter.
------
Use a proportion:
x inches / (8*12 inches) = 10 in / 20.5 inches
----
x = 96(10/20.5) inches
-----
x = 46.83 inches (diameter of the actual fountain)
