A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 16 1/2 centimeters. The blueprint has a scale of three centimeters to five feet. what will be the actual area of the fountain, in square feet, after it is built? Round your answer to the nearest hundredth of a square foot.

Answer 1

 area is 454.1 ft.

18cm/3cm = x/4ft.
x = 24 ft.

Then find the area using A=pi*r^2
A=pi*144
A=452.4 ft.
