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 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)
Assuming the pool is circular with diameter 38 feet, then the circumference equals (pi) x diam/4 = 3.14 x 38/4 feet = 29.83 feet.
fifty-six The circumference of an 18-foot diameter circular swimming pool is: 56.55 feet
C=pi*diameter so your diameter equals 27 divided by pi, or about 8.59 ft

Circumference of the circular pool: 20*pi feet

36 ft ie 2 x sqrt324
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.

Bottom of the pool is circular in shape and its radius is 9 feet. Thus area of bottom of pool = pi x r2 = 3.14159265 x 92 = 254.469005 sq. feet
diameter = 220/pi meters
The answer is 1373.75
