Question

The diameter of an above ground circular swimming pool is 30 ft.

What is the CIRCUMFERENCE of the pool?

Use 3.14 for π.

Answer 1

The formula to calculate the circumference of a circle is given by
`\displaystyle\sf C=2\pi r`, where
`\displaystyle\sf C` represents the circumference and
`\displaystyle\sf r` is the radius of the circle.

Given that the diameter of the above ground circular swimming pool is 30 ft, we can find the radius by dividing the diameter by 2. So, the radius
`\displaystyle\sf r` would be
`\displaystyle\sf (30)/(2)=15` ft.

Now, substituting the value of
`\displaystyle\sf r` into the formula, we have:

`\displaystyle\sf C=2\pi ( 15)`

Using
`\displaystyle\sf \pi =3.14`, we can calculate the circumference:

`\displaystyle\sf C=2( 3.14)( 15)`

`\displaystyle\sf C=2( 3.14)( 15)`

`\displaystyle\sf C=94.2` ft

Therefore, the circumference of the pool is 94.2 ft.
