Answer:
The length of aluminium surrounding the pool is 94.20 ft.
Step-by-step explanation:
The picture represents the circular swimming pool that has walls of aluminium surround it.
The circumference of a circle is the distance around a circle. It is the curved line that goes round the circle. The question wants us to find the circumference of the aluminium surrounding the circular pool.
circumference of a circle = 2πr
circumference of a circle = 2 × 3.14 × 15
circumference of a circle = 30 × 3.14
circumference of a circle = 94.2 ft
The length of aluminium surrounding the pool is 94.20 ft.
