The area of a circular shape is equal to 3.14 times the radius squared. For this pool it's equal to 3.14 x 9 feet x 9 feet or 254.5 square feet.
The circumference of an 18-foot circular swimming pool is: 56.55 feet.
Per Intex it's 1780 gallons at 26" high.
9ft
200.96 square 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.
Only circular shapes have diameter not Squares.
The approximate area of a circle with a 12-inch diameter is: 113 square inches.
The approximate area of a circle with a diameter of 60 centimeters is 2,827.43 square centimeters.
A circular shape with an area of 65 square feet has a diameter of 9.1 ft approx.

The circle.
201.06 square centimeters.
706.86 square inches
It is about 8 centimeters
Area of any circle = (pi) x (radius)2Radius = 1/2 of the diameterArea of the placemat = (pi) x (21)2 = 441 pi = 1,385.4 square centimeters = 0.13854 square meter
