Circumfence 2 x 15 x pi = 94 feet 3 inches
Assuming Pool is circular shape and 15 foot is diameter:
(3.14 )* 15 = perimeter of pool. (47.1 foot)
So 3 full ropes of 15 foot each plus 2.1 foot long rope
If the pool is square shaped with side measuring 15 foot,
then 4 ropes would be needed.
Circumference equals 2*pi*radius or diameter*pi
A 30-foot round pool has a circumference of about 94 feet 3 inches.
The circumference of a 21 foot round pool is approximately 65.97 feet.
15X22/7 =42.86 feet

30 feet!
The circumference is 188 feet.

The circumference of a 30-foot diameter circle is: 94.248 feet.
1,770 gallons 10x10x3x5.9=
26,550 gallons.
Approx. 20k gallons.

Not likely
circumference = 30*pi = 94.248 feet rounded to 3 decimal places
To find the gallons in a 30 foot round pool you need to: To take the radius (15) and square it (15 X 15) = 225 X pi 3.14 = 706 X a constant (7.5) = 5298 X the debth 4.5 feet = 23,844 gallons.
Cannot be answered with only these measurements. You need to specify what shape the pool is. Also, for a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.
