A circular fish pond is surrounded by a circular border of stones that is 18 inches wide. The fish pond is 4 feet in diameter. What is the area of the border? (Use 3.14 for pi)

18 inches=1.5 ft

Since the border extends around the entire circumference, it adds 3 ft to the total diameter of the border and pond.

3.14*3.5^2=38.465

Subtract the area of just the pond from this

3.14*2^2=12.56

38.465-12.56=25.905

Final answer: 25.905 ft^2
