Circumference of the circular pool: 20*pi feet
Note that the question is asking about the area of the bottom of the pool.. which by the question we can see is a cylinder shaped pool.. The bottom of the pool is a circle so, area of circle = (pie)r2 (where are is the radius) 1 diameter = 2 x radius 8 feet diameter = 4 feet of radius so the answer will be = 3.142 x 4 x 4 ( 4 is multiplied to time because the formula is r2 [note the square on the r] ) = 50.272 (Answer ) Approximate area of the bottom of the pool is = 50 square feet.
Area: pi times 50 squared = 7854 square cm rounded to the nearest integer
50.266
The volume of a cylinder is the area of its base multiplied by the height. [In this case, the "height" of the cylinder is the depth of the pool.] The base of the pool is a circle with radius of 9 m. The area of a circle is the radius squared times pi, which in this case is 81*pi m^2. Multiply this by the depth of 3.5 and you get 283.5 * pi cubic meters.
If it is a rectangular pool, then multiply the length by the width. If it is a circular pool then the surface area = (Pi/4)*(diameter^2)
diameter = 220/pi meters
Assuming a circular pool, divide the diameter by 2 to get the radius, then use the formula for the area of a circle. The depth is not relevant for this problem.

If you know the area of a pool then you need to multiply it by the height of the pool, then multiply by 7.48 to get gallons.
The diameter of a pool ball is 2 and 1/4 inch diameter. The radius of a pool ball is 1 and 1/8 inches. The radius is one half of the diameter.
C=pi*diameter so your diameter equals 27 divided by pi, or about 8.59 ft
If the pool is 25' in diameter, how does it also have 4 walls? This does not make sense, as a cylinder (round pool) only really has one wall.
The answer is 1373.75
