The formula used is: [tex]d = \frac{C}{ \pi }[/tex]
The diameter is 17.83 feet
Solution:
Given that,
Circumference of pool = C = 56 feet
To find: diameter (d)
The circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where "r" is the radius of circle
We know, that diameter is twice the radius
[tex]d = 2r[/tex]
Thus the formula becomes,
[tex]C = \pi d[/tex]
Rearrange for "d"
[tex]d = \frac{C}{ \pi }[/tex]
Substituting the values we get,
[tex]d = \frac{56}{3.14} = 17.83[/tex]
Thus the diameter is 17.83 feet
