Answer:
179 sq feet
Explanation:
What is the approximate area of the walkway?
area of walkway = area of walkway + fountain - area of walkway
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
radius of the fountain = 16/2 = 8
area of walkway + fountain = (22/7) x (8 + 3)^2 = 380.3
area of fountain = 22/7 x 8^2 = 201.1
area of walkway = 179
