Given:
A hotel swimming pool is made up of four semicircles and a square.
We need to determine the perimeter of the swimming pool.
Perimeter of the semicircle:
The perimeter of the semicircle can be determined using the formula,
[tex]P=\frac{\pi d}{2}[/tex]
The diameter of the semicircle is 12 yd.
Substituting, we get;
[tex]p=\frac{(3.14)(12)}{2}[/tex]
[tex]p=18.84 \ yds[/tex]
Thus, the perimeter of the semicircle is 18.84 yards.
Perimeter of the swimming pool:
The swimming pool consists of 4 semicircles.
Thus, we have;
[tex]Perimeter=4(18.84)[/tex]
[tex]Perimeter=75.36 \ yards[/tex]
Rounding off to the nearest tenth, we get;
[tex]Perimeter = 75.4 \ yards[/tex]
Therefore, the perimeter of the swimming pool is about 75.4 yards.
