Assuming the fountain is round.
Let r = radius
Given r = 10 ft
Find area of the base of the fountain.
Area = πr² = π(10)² = 100π ≈ 314 sq ft
The answer is 1) 314 sq ft.

I think you are saying the fountain is circular. If so, the area is
pi*r^2= pi+10^2 = 100 *pi = 314 sq ft.

I assume it is a circular base. r=10; A=Î r^2=Î *10^2=314 ft^2
1) 314 sq ft is correct.
