Answer:

Option 3rd is correct

the circumference of the a circular swimming pool is, 88 ft

Explanation:

Circumference of the circle(C) is given by:

$C = 2 \pi r$

where,

r is the radius of the circle.

As per the statement:

A contractor is building a circular swimming pool. The radius of the circle 14 feet.

⇒ r = 14 ft

Substitute the given values in [1] we have;

$C = 2 \cdot (22)/(7) \cdot 14 = 2 \cdot 22 \cdot 2$

Simplify:

C = 88 ft

Therefore, the circumference of the a circular swimming pool is, 88 ft
