From the definition of circumference:
circumference = pi*diameter
OR
circumference = pi*2*radius
Therefore,
radius = circumference/(2*pi)
radius = (50 feet)/(2*3.14159) = 7.96 feet

The formula for find the circumference of a circle is C=Ïd, and radius is 1/2 the diameter. Since we know the circumference is 50 we can find the diameter
50=Ïd
d=15.924 ft.
r=1/2(d)
r=1/2(15.924)
r=7.962 feet

radius of the fountain= 50 feet/3.1415927...
3.1415927.. is how many times the radius can fit in the circumference of a circle.
radius= 15.9154

radius = circonference/ 2 *pi pi = 3.1416
here r = 50/6.2832 = 7.95 ft

pi x D = 50
D = 50 / pi
D =15.92
r = D /2
r =7.9617 ft
