Answer:
39.29 ft
Step-by-step explanation:
We are made to know that the fountain contains two semi circles and a quarter-circle.
This means the fountain contains a total of 1+1/4 = 1.25 circles
Interestingly, the circles are similar and have the same diameter.
Now the perimeter of a circle with diameter 10ft is simply πd = 10 π
Now, since we have a total of 1.25 circles, the total perimeter would be 1.25 * 10 π = 12.5 π ft
With π as 22/7, the actual value of the perimeter would be 39.29 ft
