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 pi=22/7

Answer 1

The circumference is 43.96 feet long. Hope this helps!

Answer 2

Circumference of the circle 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 feet

Substitute the given values in [1] we have;

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

⇒
`C=2 \cdot 22 \cdot 2`

⇒
`C=88` ft

Therefore, the circumference of the circle is, 88 ft
