Question

A contractor is building a circular swimming pool. The radius of the circle 14 feet. He needs to know the circumference in order to buy tile to put around the edge of the pool. What is the circumference if he uses =22/7 ?

44ft
616ft
88ft

Answer 1

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
