Answer:

2.5 feet

Step-by-step explanation:

Circunference= [tex]C = \pi d[/tex]

15.7 = 3.14 · [tex]d[/tex]

[tex]\frac{15.7}{3.14}[/tex] = [tex]d[/tex]

5 = [tex]d[/tex]

And,

[tex]d = 2r[/tex]

So,

[tex]5 = 2r[/tex]

[tex]\frac{5}{2}[/tex]= r

2.5 = r

Answer:

2.5 feet

Step-by-step explanation:

Circumference = 2πr

Solving :

  • 15.7 = 2 x 3.14 x r
  • 5 = 2r
  • r = 5/2
  • r = 2.5 feet
