# What is the circumference of a 18ft diameter pool?

Assuming the pool is a perfect circle, it is 18 x pi feet or about 56.55 feet.

### What is the diameter of a circle if the circumference is 18 feet 8 inches?

the formula to start off with is the circumference is pi x diameter therefore re-arranging the formula the diameter is the circumference divided by pi diameter = circumference / pi = 18ft 8in / 3.1415 = 5ft and 11 inches to the nearest inch (to be more precice to diameter is 5ft 11.3 inches--- note it is more difficult to work in feet and inches and easier to work in metres and centimetres)

### How do you get a circumference and diameter with pi?

Pi represents the ratio of the circumference of a circle to its diameter. If you know the diameter (D), then the circumference (c) is (D) *pi. If you know the circumference (C), then the diameter (D) is (C)/pi. circumference is 2PiR R is the radius. so 2R is twice the radius (a.k.a. The Diameter) That leaves you with Circumference=Diameter*Pi The circumference can be found by multiplying the diameter by pi, and the diameter can be…

### If a pool is 30ft around how wide will the pool be?

About 9 ft 7 inches. In a circle, the widest point will be its diameter. The distance round the circle is called its circumference (30 feet for your pool), and that is the diameter multiplied by pi. So the diameter is the circumference divided by pi. Pi is a never-ending number, but we'll use the short version of 3.142. So the diameter of your pool is 30 feet divided by 3.142, or 360 inches /…
