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,
The diameter of the semicircle is 12 yd.
Substituting, we get;
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;
Rounding off to the nearest tenth, we get;
Therefore, the perimeter of the swimming pool is about 75.4 yards.
Ответ:
Neither, as the angles are all different, making the triangles not similar.
