We are given;
Radius of the fountain is 9.4 feet
We are required to determine the diameter of the fountains
We need to know that the diameter of a circle is twice the radius of the circle.
That is;
Diameter = 2r
Therefore;
Diameter of the fountain = 2 × 9.4 feet
= 18.8 feet
Thus, the diameter of the fountain is 18.8 ft
