The diameter of the pool is 4
Explanation:
To calculate the diameter we must write the values given in the question, here
The circumference of the pool is given as C=12.56 feet.
To calculate the diameter of the pool,
If radius is given, Multiply the radius by 2
If Circumference is given divide the circumference by Pi (π)
the constant value for Pi (π)=3.14
Diameter(D)= C/π
12.56/3.14
=4
The diameter for the plastic wading pool is 4
