Ahotel swimming pool is made up of four semicircles and a square. find the perimeter of the swimming pool. round your answer to the nearest tenth.

≈102.83 yd

Step-by-step explanation:

area of a circle=2pi(r)

2(pi)5x4

=125.66/2(semicircle)

=62.83

+10x4

=40

62.83+40=102.83

The perimeter of the swimming pool is:

                        102.8 yards

A hotel swimming pool is made up of four semicircles and a square.

This means that the perimeter of swimming pool is equal  to the sum of the perimeter of 4 semicircle and a square.

We know that the perimeter of a semicircle is given by:

where r is the radius of the semicircle

Hence, Perimeter of 4 semicircle is:

Radius of semicircle= 5 yard

( since diameter= 10 yard)

Hence,

and Perimeter of square is: 4×10=40 yards.

Hence, the Perimeter of swimming pool is: 62.8+40=102.8 yards
