Area = pi*r2
r = Diameter/2
r = 6.5 meters/2
= 3.25 meters
--------------------------now,
Area = pi(3.25 meters)2
= 33 m2

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
To measure for a round pool, start by determining the desired diameter by measuring the distance across the area where you plan to place the pool. Use a measuring tape to find the radius by dividing the diameter by two, then ensure you have at least a few extra feet around the edges for safety and maintenance access. Finally, check for any underground utilities or obstructions in the area before finalizing your measurements.

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)
To find the area of a circular pool, you can use the formula ( A = \pi r^2 ), where ( r ) is the radius. The radius is half of the diameter, so for a diameter of 5 feet, the radius is 2.5 feet. Therefore, the area is ( A = \pi (2.5)^2 \approx 19.63 ) square feet.
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.
