Answer 1

62.8

Explanation:

d=10

10x3.14

31.4

31.4x2

62.8 is the perimeter

Answer 2

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,

`P=(\pi d)/(2)`

The diameter of the semicircle is 12 yd.

Substituting, we get;

`p=((3.14)(12))/(2)`

`p=18.84 \ yds`

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;

`Perimeter=4(18.84)`

`Perimeter=75.36 \ yards`

Rounding off to the nearest tenth, we get;

`Perimeter = 75.4 \ yards`

Therefore, the perimeter of the swimming pool is about 75.4 yards.
