Answer:
75.40 feet
Step-by-step explanation:
For the two small semicircles, the circumference is
, or just
. Since the radius is 1/2(16), or 8, the combined circumference of the two semicircles is 16
. Now, for the area of the quarter circle in the middle, we see that its radius is 16, and so its circumference is
, or
= 8
. So, the perimeter of the fountain is 16
+ 8
= 24
, or about 75.40 feet.
