# What is the radius of an 18ft circumference pool?

since c of the pool is 18

then 2pieR = 18

/2

pieR=9

/pie

R=9/pie

the radius is 9/pie

### How many yards is around a 24 ft round pool with a 2 ft edging around it?

The circumference of the pool is 24 ft so its radius is 24/(2*pi) = 3.8 ft.Then radius of pool + edging = 3.8 + 2 = 5.8 ft. So circumference around edging = 36.6 feet = 36.6/3 = 12.2 yards. The circumference of the pool is 24 ft so its radius is 24/(2*pi) = 3.8 ft.Then radius of pool + edging = 3.8 + 2 = 5.8 ft. So circumference around edging = 36.6 feet…

### My pool is 18 feet around and 4 feet deep - how many gallons of water does it hold?

18ft = Circumference = 2*pi*radius -> radius = circumference/(2*pi) = 18/(2*3.14...) = 2.865 Volume of a cylinder = depth*pi*radius2 = 4ft*3.14...*2.8652 = 103.13 ft3 Google says that 1 cubic foot = 7.48051948 US gallons 103.13ft3*(7.4805gallons/ft3) = 771.46 gallons The volume of the pool is 771.46 gallons.
